What Is Sodium Hydroxide’s PKa?

With a pKa of 13.8 sodium hydroxide is a strong base. Sodium hydroxide, popularly known as lye or caustic soda, has the chemical formula NaOH. It’s an alkali salt and an organic substance.

Sodium hydroxide is the conjugate base of water, according to Master Organic Chemistry’s James Ashenhurst. With a pKa of 15.7, water is a weak acid. Water and the equivalent salt are produced when sodium hydroxide combines with protic acids, such as hydrochloric acid. In the instance of a reaction with hydrochloric acid, the products are water and sodium chloride. HCL, or hydrochloric HCl, is a strong acid with a pKa of -8. The difference in pKa between water and HCL is about 24. This acid-base reaction is favoured by the significant pKa difference and is essentially irreversible.
