1. The pH of an acid solution is 5.52. calculate Ka for the monoprotic acid with initial concentration of .010 M.
2. calculate percent ionization of benzoic acid for a .7 M and a .0007 M solution.
3. If the original concentration of HCOOH was .4 M and the toal molarity of particles at equilibrium is .406 M, what is the concentration of HCOOH at equilibrium?
4. what is the original molarity of a solution of amonia whose pH is 11.35?
