The laboratory procedure is as follows:

Mix 2 grams of salicylic acid with 4 milliliters of acetic anhydride in a 125 milliliter Erlenmeyer flask.
Add 3 or 4 drops of concentrated sulfuric acid to the flask and stir.
This is an exothermic reaction and so heat will be liberated when the reaction starts. If the flask does not warm, add another drop of acid to the flask until the heating effect begins.
Once the heating effect is detected, heat the reaction mixture in a water bath at 50 degrees centigrade for 5 minutes in order to drive the reaction to completion.
Cool the flask and then ADD 40 MILLILITRES OF WATER. Stir the aqueous mixture until a solid is formed and becomes well dispersed in the liquid.
Filter the liquid by suction using a Hirsch funnel and wash with cold water.
Use hot water to crystallize the filtrate.
If necessary use carbon to decolorize.
WHAT IS THE WATER USED FOR?

increasing the concentration of reactant will increase the rate of a reaction.if a piece of magnesium ribbon is added to a solution of ethanoic acid the following reaction occurs.
magnesium + ethanoic acid = magnesium ethanoate

make a predication about what you think will happen when you react.Mg with different concentration of acid(0.5m,1.0m,1.5m,2.0m,2.5m) predict what the graph will look like.

explain your predictions using scientific theory ie collision/particle theory.
