What is the precipitating agent used in the "Gravimetric Determination of Chloride" experiment?

• Silver chloride

• Silver nitrate

• Nitric acid

• Sodium chloride

Name the precipitate formed in the experiment.

• Silver nitrate

• Silver sulphate

• Silver chloride

• Sodium chloride

What is the purpose of heating the solution in the experiment?

• To form more precipitate

• To help in the coagulation process

• To remove the impurities of the product

• To produce a smaller particles of precipitate

State the reason for placing the heated solution in a dark place.

• to reduce the effect of sunlight in the formation of precipitate

• To allow the precipitate to produce larger particles

• to enhance the production of a uniform size precipitate

• To avoid photodegradation of the product formed

What is the reason for washing the precipitate using dilute acid solution?

• to transform the precipitate into larger particles

• to avoid crystallization of the product

• To avoid peptization of the precipitate

• to remove the impurities from the precipitate
