Q. The heat of neutralisation of a strong base and a strong acid is 13.7 kcal. The heat released when 0.6 mole HCl solution is added to 0.25 mole of NaOH is

NTA AbhyasNTA Abhyas 2022 Report Error

Solution:

For the neutralization between a strong and a strong base, equal number of moles of (from acid) and (from base) come out. For one mole of following equation can be drawn

So, 0.25 mole of is produced.
So, heat released
