Rates of reaction

A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid.

Task

My task is to measure the rate of reaction between marble chips (CaCO3) and Hydrochloric acid (2Hcl).

Plan







The equipment I will be using for this experiment will be as follows: Conical flask, Delivery tube, Bung, Measuring cylinder X2, Water trough, Water, Stopwatch, Marble chips, Hydrochloric Acid, water scales, clamp and Retort Stand.

!△WEAR SAFETY GOGGLES△!

I will fill the water trough ¾ full of water and 1 measuring cylinder completely full. When I have done this I will cover the top of the full measuring cylinder, tip it upside down, insuring that no air escapes in to the cylinder. I will no place the measuring cylinder into the water and leave to rest. I will now measure out 50ml of 2Moler Hydrochloric Acid into my 2nd measuring cylinder, and then pour it into the Conical flask. I will next weigh ...
