At half neutralisation of weal acid with a strong base,what is the relationship between `pH` and dissocaition constant `(K_(a))` of weak acid ?

What is the relationship between pK_(a) and K_(a) of an acid ?

Enthalpy of neutralisation of all strong acids and strong bases has the same value because

The heat of neutralization for a strong acid by a strong base is a constant

Why is heat of neutralisation for a strong acid and strong base constant ?

The heat of neutralization of a strong acid by a strong base is a constant because :

Heat of neutralization of strong acid against strong base is constant and is equal to

Is the process of neutralisation of a strong acid by a strong base a redox process ?

The enthalpy of neutralisation of a weak acid in 1 M solution with a strong base is -5.6 kJ mol^(-1) . Enthalpy of ionization of the acid is 1.5 kJ mol^(-1) and enthalpy of neutralization of the strong acid with a strong base is -57.3 kJ"equiv"^(-1) , what is the % ionization of the weak acid in molar solution (assume the acid to be monobasic) ?
