Plan
Aim
In this investigation I will react marble chips and varying concentrations of Hydrochloric acid and measure the rate of reaction to see what the effect of different concentrations have on the rate of reaction.
Equation
I already know that carbonates react with acids to produce Water, Carbon Dioxide and a salt:
CaCO3(s) + 2HCl(aq) => CO2(g) + CaCl2 (aq) + H2O(l)
Method
Equipment
I will need :
- A gas syringe
- A bung and tube
- A conical flask
- Marble chips
-
Hydrochloric acid (2mol/dm3)
- A measuring cylinder
- A retort ...
