Hydrochloric acid and marble chips experiment

The aim of this experiment is to find out how different variables this reaction between marble chips (calcium carbonate) and hydrochloric acid is an exothermic reaction these are reactions that transfer energy to the surroundings the energy is usually transferred as heat energy, causing the. What are the possible systematic errors and random errors that could affect the results when all other factors that could affect the rate of reaction are kept constant except for the concentration. A student investigated the rate of reaction between marble chips and hydrochloric acid (hcl) figure 1 shows the apparatus the student used sketch a line on the grid in figure 2 to show the results you would expect if the experiment was repeated using 20 g of smaller marble chips. The aim of this experiment is to investigate how different concentrations of one type of reactant (hydrochloric acid) affect the rate of reaction between marble chips (caco3) and hydrochloric acid (hcl) by measuring the volume of carbon dioxide (co2) produced.

Calcium carbonate is dissolved by hydrochloric acid, thereby forming gaseous carbon dioxide: the combined reactants have a higher chemical potential than the combined products, ie the reaction takes place spontaneously. Marble chips and hydrochloric acid experiment i have a booklet for school due very soon i need to write a method up for this experiment as well as explaining what the controlled variable, independent variable and dependent variable is. Marble is primarily made of calcium carbonate vinegar has acid in it when the weak acid contacts the calcium carbonate, it gives off bubbles of carbon dioxide gas, and eventually will erode the surface of the marble chips.

You are going to collect and analyse data to find the order of this reaction with respect to hydrochloric acid. The marble chips are completely used up, in every case the results are used to draw graphs of the volume of carbon dioxide produced against time please note: for each experiment, assume that the hydrochloric acid is in excess. Practical work for learning carry out the experiment b the reaction of marble chips with hydrochloric acid is first order with respect to hydrochloric acid r hcl = k [hcl] orders of reaction are experimental quantities they cannot be deduced from the chemical equation for the reaction. 44 rate of reaction: marble chips and hydrochloric acid read when marble chips (calcium carbonate) react with an acid they produce carbon dioxide gas, calcium add the marble chips to the acid, and repeat the experiment from step 5 using a different grade of marble chip make sure you reset the bubble counter to zero l3 chemistry.

React hydrochloric acid and marble chips measure the volume of gas evolved with a gas syringe and take readings at regular intervals repeat experiment with same volume of acid and mass of marble chips, but with marbles more crunched. Hydrochloric acid and marble chips experiment essay hypothesis: the higher the concentration of hydrochloric acid, the faster the reaction will take place because there will be more hydrochloric acid particles to collide with the marble chip particles therefore resulting in a quicker reaction - hydrochloric acid and marble chips experiment essay introduction. Rate of reaction between marble chips and hydrochloric acid to investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail scientific knowledge: marble chips erode when they are exposed to acid rain or pollution. What is the reaction of hydrochloric acid and marble chips often used to demonstrate the effect of increasing the surface area of a solid 1 of 7 what do you do first with the reaction of hydrochloric acid and marble chips experiment (1) 1) measure the volume of gas evolved with a gas syrine and.

- rates of reactionsin marble chips investigation aim --- the aim of this experiment is to discover how the rate of reaction between marble chips and hydrochloric acid changes as the concentration of the acid is increased or decreased. To observe the effect of surface area (particle size) on the rate of reaction between marble chips (calcium carbonate) and hcl 3bto observe the effect of surface area (particle size) on the rate of reaction between magnesium ribbon and hydrochloric acid. We can investigate the effect of surface area on reaction rate by looking at the reaction between marble chips and dilute hydrochloric acid an acid is a substance that forms a solution with a ph value of less than 7. Be given details about the conditions for six different experiments in which marble chips were added to hydrochloric acid and some graphs showing the volume of gas produced over a period of time select which graph is most likely to be produced in the different conditions.

Hydrochloric acid and marble chips experiment

In the reaction between calcium carbonate (marble chips) and hydrochloric acid we can use the apparatus below to find the rate of reaction marble chips and acid are placed in the flask but separated by a piece of card - preventing the reaction from proceeding. A simple experiment using the ethanedioate (oxalate) in rhubarb stems to decolourise acidified permanganate and to investigate the effect of surface area seems more approachable and relevant to students than marble chips dissolving in acid. Marble chips, and the concentration and volume of hydrochloric acid used, were the same for both experiments the flask was connected to an inverted measuring cylinder in a basin of water, as shown in.

  • The rate of reaction between hydrochloric acid and marble chips essay - the rate of reaction between hydrochloric acid and marble chips plan in this experiment, i will be investigating the rate of the reaction between hydrochloric acid (hcl) and marble chips.
  • Chemistry coursework by mohammad yousuf 10u investigation of the reaction between marble chips & dilute hydrochloric acid calcium carbonates which are marble chips react with hydrochloric acid to give out calcium chloride, water and carbon dioxide.
  • Balance marble chips 20 m hcl purpose: the purpose of this experiment is to obtain mass data related to a chemical reaction and illustrate the use of excel spreadsheets as a tool in the analysis of such data.

An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. Lime water is also known as calcium carbonate calcium carbonate reacts with hydrochloric acid and produces a gas called calcium carbonate hyphole acid which slowly deteriotes the marble chips. Prediction i predict that the more marble chips there are, the faster the rate of reaction, because there is more marble for the hydrochloric acid to react with, i predict this because in previous experiments when working with the same equipment i found that if you put a lot of marble in the acid, the levels of water in the burette go down very quickly, compared to when you only put a little. In this reaction, it is expected that as marble chips are in the solid form, and their concentration does not change, the rate will only depend upon the concentration of hydrochloric acid, and is likely to be first order with respect to hcl.

hydrochloric acid and marble chips experiment Hydrochloric acid is poured onto chips of calcium carbonate in a test tube the vigorous reaction between them produces carbon dioxide gas (and calcium chloride and water, neither seen), which passes up the tube and into a beaker of clear limewater. hydrochloric acid and marble chips experiment Hydrochloric acid is poured onto chips of calcium carbonate in a test tube the vigorous reaction between them produces carbon dioxide gas (and calcium chloride and water, neither seen), which passes up the tube and into a beaker of clear limewater. hydrochloric acid and marble chips experiment Hydrochloric acid is poured onto chips of calcium carbonate in a test tube the vigorous reaction between them produces carbon dioxide gas (and calcium chloride and water, neither seen), which passes up the tube and into a beaker of clear limewater. hydrochloric acid and marble chips experiment Hydrochloric acid is poured onto chips of calcium carbonate in a test tube the vigorous reaction between them produces carbon dioxide gas (and calcium chloride and water, neither seen), which passes up the tube and into a beaker of clear limewater.
