10 mL of a strong acid (HA) on mixing with 10 mL of strong alkali (BOH) at the same temperature shows a temperature rise of 4°C. If 50 mL of the same acid is mixed with 50 mL of the same alkali, the temperature rise will be … °C. Assume all the heat produced is used up in increasing the temperature of the mixture only.

Answer: 4

Solution

Scaling both volumes by the same factor keeps the acid:base ratio and concentrations unchanged, so both the heat released and
