Determination of Heat of Neutralization of NaOH and HCl | enthalpy of neutralization of NaOH and HCl

To determine the Heat of neutralization of NaOH and HCl
To determine the Water Equivalent of Calorimeter
The Heat capacity of a system is its capacity to absorb heat and store energy. As the system absorbs heat, the atoms and molecules contained in the system starts vibrating or their kinetic energy increses. This increased kinetic energy raises the temperature of the system.
Procedure
Heat water to about 50 oC in a beaker.
Measure out 50 ml of this water into the calorimeter place the thermometer in it and keep stirring.
Take temperature readings at every ½ min intervals about 3 min.
Meanwhile measure 50 ml of cold water and note its temperature.
At a noted time, add the cold water into the calorimeter and stir thoroughly.
Continue taking temperature readings at ½ min interval for next 3 more min.
Heat gained by cold (water + Calorimeter) body = Heat lost by hot body
