The relationship between the degree of ionization of weak base or weak acid and equilibrium constant and initial concentration of acid or base has to be determined. Concept Introduction: Degree of ionization of a weak acid or weak base can be determined by writing the equilibrium concentration of all species involved in the equilibrium. From the relationship of the equilibrium constant, the degree of ionization and initial concentration, the value of the degree of ionization of ammonium ion can be determined.

Methanoic acid is also called formic acid. It has the chemical formula HCOOH(l). It is a colourless fuming liquid that is mainly used as a preservative. It exhibits the following equilibrium in water:HCOOH(aq) + H2O(l) → HCOO–(aq) + H3O+(aq)
4) The concentration of the hydroxide ion, OH-(aq), in an aqueous solution is 2.5 x 10–3 mol/L. What is the pH of the solution?
PLEASE HELP THIS IS VERY URGENT
