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 11
A student mixes solutions of sodium sulfate and barium chloride. What is the name of the salt that precipitates?
A student wants to prepare lead(II) sulfate. Which method should they use?
Describe the difference between preparing a soluble salt and an insoluble salt.
Describe the process of preparing an insoluble salt using a precipitation reaction.
Describe the steps involved in preparing copper(II) sulfate crystals from copper(II) oxide and sulfuric acid.
Explain why excess base is used when preparing a salt from an insoluble base and an acid.
Explain why filtration is used after reacting an insoluble base with an acid in salt preparation.
Explain why silver chloride cannot be prepared by reacting silver with hydrochloric acid.
Explain why titration is used to prepare salts involving soluble acids and soluble bases.
A chemist wants to prepare a pure sample of magnesium sulfate. They have access to magnesium oxide and dilute sulfuric acid. Which method should they use, and why is it important to use an excess of one of the reactants?
A solution of barium chloride is added to a solution of sodium sulfate. Write the balanced chemical equation for the reaction and identify the precipitate formed.
A student is given dilute sulfuric acid and solid zinc carbonate. Describe the steps required to prepare pure zinc sulfate crystals from these reactants, including how to ensure the final product is free from impurities.
Describe the process and reasoning behind using crystallization to obtain pure salts from a solution after a neutralization reaction.
Explain why it is not possible to prepare calcium sulfate by reacting calcium carbonate with sulfuric acid in a one-step reaction.
Explain why sodium chloride cannot be prepared by reacting sodium metal with hydrochloric acid in a typical school laboratory setting.
