titration lab report

When a weak acid reacts with a weak base, the equivalence point solution will be basic if the base is stronger and acidic if the acid is stronger. The equivalence point is characterized by a sharp change of pH which can be followed with a pHmeter. The point observed experimentally is never exactly the molar equivalence but a “best estimate” and is given the name “end point”. You’ll perform titration experiments to work out the level of ammonia in the samples. Chemistry report final Asyh Syiedah. Reaction of acid and base is one of the most common reaction in chemistry.
