Heat of Neutralization 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 Heat of Neutralization. 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

Describe how the heat of neutralization can be used to distinguish between strong and weak acids.

Describe the process of measuring the heat of neutralization in a laboratory experiment.

Explain why the heat of neutralization for the reaction between a strong acid and a strong base is nearly constant.

Explain why the heat of neutralization for the reaction between a weak acid and a weak base is even less exothermic than that for a weak acid and a strong base.

A calorimeter contains 100 g of water at 25°C. When 0.1 mol of HCl is neutralized by 0.1 mol of NaOH, the temperature rises to 26.4°C. Calculate the heat of neutralization per mole. (Specific heat of water = 4.18 J/g°C)

A student adds 25 mL of 2 M HCl to 25 mL of 2 M NaOH. The temperature increases by 5°C. Calculate the heat evolved. (Assume density = 1 g/mL, specific heat = 4.18 J/g°C)

A student mixes 100 mL of 1 M HNO₃ with 100 mL of 1 M KOH. The temperature increases by 7°C. Calculate the heat of neutralization per mole of water formed. (Assume density = 1 g/mL, specific heat = 4.18 J/g°C)

Calculate the heat of neutralization per mole if 0.2 mol of HCl reacts with 0.2 mol of NaOH and releases 11.4 kJ of heat.
