Hydrolysis of Salts
Chemistry ⇒ Acids, Bases, and Salts
Hydrolysis 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 Hydrolysis 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 solution contains a salt formed from a weak acid and a weak base. Predict the pH of the solution.
A solution of ammonium nitrate (NH₄NO₃) has a pH less than 7. Explain why.
