A 50.0-g sample of a dilute acid solution is added to 50.0 g of a base solution

Question:

A 50.0-g sample of a dilute acid solution is added to 50.0 g of a base solution in a coffee-cup calorimeter. The temperature of the liquid increases from 18.20 °C to 21.30 °C . Calculate q for the neutralization reaction, assuming that the specific heat of the solution is the same as that of water (4.184 J/g · °C).

Strategy

Use the temperature change and Equation 5.4 to determine the heat released by the reaction. Be careful to correctly determine the mass of the solution.

Equation 5.4q = mCAT
