how to add nmultiple K values together?

To combine multiple K values, you multiply the equilibrium constants for the reactions that add together, adjusting for stoichiometry if necessary.

Kc new =Kc1* Kc2*c3…

Buffer solution

A buffer solution is a system that resists changes in pH when small amounts of acid or base are added. It typically consists of a weak acid and its conjugate base, or a weak base and its conjugate acid.

pKa and pH

pH = pKa + log( [A-] / [HA])
