I will be investigating how the concentration of hydrochloric acid affects the rate of reaction between hydrochloric acid and magnesium ribbon. Equation: Mgs+2HClaq→MgCl2aq+H2g Planning: The input variables are: ?óÔé¼?ó temperature of acid ?óÔé¼?ó concentration of acid ?óÔé¼?ó surface area of magnesium ?óÔé¼?ó use of catalyst I will measure the concentration of acid and control the temperature of acid, surface area of magnesium, mass of magnesium and use of catalyst. The temperature of the acid will effect the rate of reaction because as the acid particles heat up, they gain...
try to make our data more accurate by using a syringe to measure small amounts of acid and water, and using as many decimal places as we could in our calculations.

The temperature of the acid was hard to control, as it was controlled by the temperature of the room.

If I was to repeat the experiment, I would use more varied concentrations in order to show more clearly the pattern, and also to attempt to clear any anomalies. I would also like to investigate larger concentrations of acid, but would have been hard to measure.
