Marble Chips And Hydrochloric Acid Reaction

In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.

Marble chips and hydrochloric acid reaction. The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o. I also predict that the more dilute the acid is the more. Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.

2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. I will use concentrations of 50cm3 using different volumes of water and acid. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid. Hcl calcium carbonate calcium chloride carbon dioxide water.

This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide. The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. Diagram plan the equipment i will be using for this experiment will be as follows.

I predict that the more hydrochloric acid there is the faster the chemical reaction. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. δh 20c 79 9kj positive so the reactio. Marble chips experiment pilot aim.

Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.
