Neutralisation
AIM:to observe a neutralisation reaction
EQUIPMENT: a test tube,test tube rack,1 mol L-1 Na2CO3 (sodium carbonate), 1 mol L-1 HCI (hydrochloric acid),dropper or dropper bottle,universal indicator solution.METHOD: add approxmately 1-2 mL of Na2CO3 and place the test tube into the test rack.Add 3-5 drops of universal indicator solution.
using a dropper bottlel, HCIdrop by drop.be careful because adding even a small ammount of extra acid can mean you'll miss the neutralisation point
OBSERVATION: in this experiment we used sulfuric acid as the acid and ammonium Hydroxide as the base.
At first test tube we added few drops of acid,1-2drops of ammonium Hydroxide and 2 drops of universal indicator.The reaction was was dark red a pH of 1 .
the second test tube we added 2 drops of acid and few drops of base and 2 drops of universal indicators. the reaction was green a oh of 7
