    Enthalpy of neutralisation of HCl with NaOH is x. The heat evolved when 500 ml of 2N HCl are mixed with 250 ml of 4 N NaOH will be-

    A) 500 x               

    B) 100 x

    C) x                                 

    D) 10x

    Correct Answer: C

    Solution :

    250 ml of 4N NaOH = 500 ml of 2N NaOH It will completely neutralize 500 ml of 2N HCl Heat evolved from 1000 ml of IN HCl = x (Given) \[\therefore \] heat evolved from 500 ml of 2N HCl = x.
