Concentration of hydronium ions

Postby NicoleJewell » Sat Dec 13, 2014 12:42 pm

If you are given the values of the molar solutions, but not provided with a Ka or pH value, how do you solve for the concentration? I understand the equilibrium concept, but I don't understand how to solve for x if you are not given the Ka or pKa value.

If these are homework questions, they will most likely refer you to tables 11.1 and 11.2 for the Ka/b and pKa/b values. I am not exactly sure how to solve it myself if you are not allowed to reference these two tables.

They will always give you the pKa, pKb, Ka, or Kb values. You just have to now how to convert between those four values.
