Enthalpy of Neutralisation

30.An aqueous...

Question

30.An aqueous solution of an acid is so weak that it can be assumed to be practically unionized when boiled at 100.4 degree Celsius. 25 ml of the solution was neutralized by 38.5 ml of 1 N solution of NaOH. What is the basicity of acid if Kb for water is 0.52 K Kg/mol?
