Chemistry - Rates Of Reaction Investigation
Chemistry Coursework – Rates of Reaction Investigation
Introduction
In this investigation I am going to be investigating the reaction between marble chips and hydrochloric acid, and to see what differences in the rate of this reaction arise when different concentrations of acid are used. Below is the word equation for this reaction:
Calcium Carbonate + Hydrochloric Acid = Calcium Chloride + Carbon Dioxide + Water
Below is the fully balanced chemical equation for this reaction.
CaCo3 + HCl CaCl2 + CO2 + H2O
Aim
The aim of this investigation is to find out whether the concentration of the acid affects the rate of reaction between the acid and marble chips.
Prediction
I predict that, as the concentration of acid in the test tube increases, so too will the rate of reaction. I think this because concentration relates to the amount of molecules in the acid, and if there is a higher concentration of acid there is a larger amount of......
