The strength of an acid or the measure of its tendency to release proton ions (H+) can be indicated from its dissociation constant which is called Ka.
The acid dissociation constant, pKa , is the negative logarithm of dissociation constant (Ka).
equilibrium constant

The dissociation constant of pure water is 1.9E-5.
Methyl orange is also known as H + In -. Its dissociation constant for its ionic strength is 0.1 mol I-1 in water, at 25 degrees Celsius.
dissociation
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].

The dissociation constant of pure water is 1.9E-5.
The dissociation of HNO3 is:HNO3-----------H+ + (NO3)-
Methyl orange is also known as H + In -. Its dissociation constant for its ionic strength is 0.1 mol I-1 in water, at 25 degrees Celsius.
Because the water dissociation is an endothermic reaction.
Because the water dissociation is an endothermic reaction.

Of course,pure water have equal concentrations of H+ and OH-.
These substances are ionic compounds forming electrolytes by dissociation in water.
Dissociation products of sodium chloride are the cation Na+ and the anion Cl-.
You think probable to dissociation constant.
