Aim: To investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid.
Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride, Water and Carbon Dioxide. The symbol equation for this is:
CaCo3 Ca2+ + Co32-
Hcl H+ + Cl-
Add these all together to get
CaCO3(s) + 2H+(aq) --> Ca++(aq) + H2O + CO2(g)
The rate of reaction is just the speed at which the substances on the left side of equation turn into the substances on the right side. The way we measured the rate of reaction today was measuring the how quickly carbon dioxide gas was produced in each experiment.
A reaction occurs when particles collide. This process is based on random particle movement. So therefore, the more particles you have in a space, the more likely they going to collide. Therefore making the reaction accelerate. This......
