Neutralization Reactions
Chemistry ⇒ Acids, Bases, and Salts
Neutralization Reactions starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Neutralization Reactions.
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 farmer adds slaked lime (Ca(OH)₂) to acidic soil. Explain the chemical reaction that takes place.
A solution of acetic acid (CH₃COOH) is titrated with sodium hydroxide (NaOH). Write the balanced chemical equation for the reaction.
A student mixes 50 mL of 1 M HCl with 50 mL of 1 M NaOH. What is the pH of the resulting solution?
Describe the role of indicators in neutralization reactions.
