the reaction between 100cm3 of 2.00moldm-3 HCl and excess of magnesium was being investigated by the continuous monitoring method. the volume of gas evolved was being monitored at set intervals as a first step in determining the order of reaction with respect to HCl.
At the point when 200cm3 of gas had been collected what was the molarity of salt in the solution and what was the molarity of the acid
Also what apparatus should i use
