Methylammonium chloride dissociates into quaternary ammonium ion (CH3NH3+) and chloride ions (Cl-). Chloride ion (Cl-) is the conjugate base of a strong acid so it will not influence the pH of the solution. Methylammonium ion is the conjugate acid of a weak base, so an acid-dissociation reaction determines the pH of the solution.
The balance equation is given below,
Ka value of CH3NH3+ is calculated,

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A student heats 60.94 grams of silver to 98.31 °C and then drops it into a cup containing 79.27 grams of water at 21.78 °C. She measures the final temperature to be 25.06 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.69 J/°C.
