CONCENTRATION OF ACID

CONCENTRATION OF ACID




Aim
The aim of this investigation is to find out how concentration of acid affects the rate of reaction between hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. It is important to remember that a rapid reaction is completed in a short period of time. Some reactions are very fast, e.g. (the formation of silver chloride precipitate when silver nitrate and hydrochloric acid solutions are mixed. In this investigation we will test different concentrations of acid reacting with magnesium.

Prediction
I predict that as the concentration of the hydrochloric acid increases, the time taken for the magnesium to disappear decreases. I predict that when the concentration of the hydrochloric acid doubles, the rate of the reaction doubles.
Linking prediction to theory
Reaction rate and concentration.
The collision theory describes how the rate of reaction increase (the time taken for the m...
