WebThe purpose of the lab was to measure the heat capacity of a salt like NaOH, the enthalpy of a neutralisation reaction such as HCl, the heat of specific metals like H2O, and the calorimeter itself. Calorimetry is a method for quantifying heat changes during chemical or physical processes. A calorimeter is a device used to measure the amount of ... WebSep 6, 2014 · C H X 3 C O O H: ( 0.1 − 0.02) mole = 0.08 mole Now, p H = p K a + log [Salt] [Acid] Hence, p H = p K a + log n Salt V n Acid V Which after plugging in the values gives, p H = 4.92.
