Rates Of Reaction Between CaCo3 and HCL of different concentrations.

What I am Doing : Aim

I am investigating the reaction of solid Calcium Carbonate with Hydrochloric Acid,

The word equation for this is,

CaCo3 + 2HCL ? CaCL2 + CO2 + H2O

I aim to produce a valid set of results to produce a good graph for evaluation.

What I Already Know

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 are to collide. Therefore making the reaction accelerate.

This theory can be proved if you compare the rates of reaction with marble in hydrochloric acid. If the acid is of a higher concentration, the reaction will be quicker.

Also if the particles have more energy, they will be travelling faster, making them collide more frequently.

Prediction

When the concentration of acid increases, more gas will be given off faster. I know this from my trial experiments.

Method

Since I will be working with acid, I will wear safety goggles while conducting the experiment.

I will use 1gram Marble chips that are all ground down to roughly the same size, and I will use 20cm3 of HCL of different concentrations ranging from 0.4M - 2M

I can measure the reaction by how much gas is given off. When the experiment takes place, I will take the reading after 2 minutes to get a graph for the results.

To be sure I can rely on my results I will repeat he ...
