AIM; TO INVESTIGATE THE RATE OF CARBON DIOXIDE PRODUCTION WITH VARYING CONCENTRATION
OF HCL ON CALCIUM CARBONATE.

INTRODUCTION;

In this experiment, I will use calcium carbonate in form of marble chips and hydrochloric acid since
when hydrochloric acid and the calcium carbonate are put…

For safety I will wear safety goggles to protect my eyes from the
possibility of the acid splashing on my face. I will also wear a
protective lab coat to stop the acid splashing and burning my clothes
and skin since acid is highly…

This makes it more reliable than a measuring cylinder. If I had used the burette my results
would be more reliable.

My readings of the amount of gas produced would have been easier to collect using a data
logo other than using the gas…

When taking my results into consideration, I think my experimental results are not reliable
because the amount of gas produced is supposed to double as you increase the
concentration of hydrochloric acid. The possible cause of my results not being reliable is that
I…
