Preparation of Salts
Chemistry ⇒ Acids, Bases, and Salts
Preparation of Salts starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Preparation of Salts.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A student adds excess zinc oxide to dilute sulfuric acid, filters the mixture, and evaporates the filtrate. What salt is obtained?
A student mixes solutions of sodium chloride and silver nitrate. What is the white precipitate formed?
A student wants to prepare magnesium sulfate. Which method should be used?
Describe how to prepare lead(II) sulfate in the laboratory.
Describe the precipitation method for preparing an insoluble salt.
Describe the role of titration in the preparation of salts.
Describe the steps involved in preparing copper(II) sulfate from copper(II) oxide and sulfuric acid.
Explain why evaporation to dryness is not suitable for preparing hydrated salts.
Explain why excess insoluble base is added to an acid when preparing a soluble salt.
Explain why it is important to wash the precipitate when preparing an insoluble salt.
Explain why some salts are prepared by precipitation rather than by neutralization.
Which method is used to prepare sodium chloride in the laboratory?
Which salt is formed when magnesium reacts with hydrochloric acid?
Which salt is formed when potassium hydroxide reacts with nitric acid?
A solution of calcium chloride is mixed with a solution of sodium carbonate. Write the balanced chemical equation for the reaction and name the salt formed as a precipitate.
Describe the difference between preparing a soluble salt using an insoluble base and preparing an insoluble salt using the precipitation method.
Describe why the direct reaction of sodium metal with sulfuric acid is not a suitable method for preparing sodium sulfate in the laboratory.
Explain why it is necessary to use an indicator when preparing a salt by titration of a strong acid with a strong base.
Explain, with balanced chemical equations, how you would prepare pure crystals of potassium sulfate starting from potassium carbonate and sulfuric acid. Include all necessary steps and precautions.
