When 2.5000 g of NaOH were dissolved in 49.0 g of water in a calorimeter at 24.0 °C, the measured temperature rose to 37.1 °C. Is this dissolving process exothermic or endothermic?

Answer :

The dissolving process of 2.5000 g of NaOH in 49.0 g water in a calorimeter at 24.0°C is exothermic since the temperature went up from 24.0°C to 37.1°C which suggests that heat was released during the dissolving process, making it exothermic.

How to determine if the reaction is exothermic or endothermic?

When 2.5000 g of NaOH were dissolved in 49.0 g water in a calorimeter at 24.0°C, and the measured temperature went up to 37.1°C, this dissolving process is exothermic. An exothermic reaction is one where heat is released, causing the temperature to rise. In this case, since the temperature increased from 24.0°C to 37.1°C, it indicates that heat was released during the dissolution of NaOH in water, making it an exothermic process.
