pH of Salt of Weak Acid and Strong Base

Go Negative Log of Hydronium Concentration = (Negative Log of Ionic Product of Water+Negative Log of Acid Ionization Constant+log10(Concentration of Salt))/2

Concentration of Hydronium ion in Weak Base and Strong Acid

Go Hydronium Ion Concentration = sqrt((Ionic Product of Water*Concentration of Salt)/Constant Of Ionization Of Bases)

Degree of Hydrolysis in Salt of Weak Acid and Strong Base

Go Degree of Hydrolysis = sqrt(Ionic Product of Water/(Constant of Ionization of Acids*Concentration of Salt))

Hydrolysis Constant in Weak Acid and Strong Base

Go Constant Of Hydrolysis = Ionic Product of Water/Constant of Ionization of Acids

pKb of Salt of Strong Acid and Weak base Formula

Negative Log of Base Ionization Constant = 14-(2*Negative Log of Hydronium Concentration)-log10(Concentration of Salt)
pk_b = 14-(2*pH)-log10(C_salt)

What is pKb scale?

The pKb is the negative base-10 logarithm of the base dissociation constant (Kb) of a solution. It is used to determine the strength of a base or alkaline solution. The lower the pKb value, the stronger the base. As with the acid dissociation constant, pKa, the base dissociation constant calculation is an approximation that is only accurate in dilute solutions.

How to Calculate pKb of Salt of Strong Acid and Weak base?
