Question
what is the concentration of hydrogen ion in a 0.1M solution of sodium hydroxide(NaOH)?
NaOH dissolves and completely dissociates in H2O to form the ions.
NaOH ==> Na^+ + OH^-
Therefore, starting with 0.1 M NaOH will give you 0.1 M in Na^+ and 0.1 M in OH^-.
You know Kw=(H^+)(OH^-)
Kw is 1 x 10^-14.
(OH^-) = 0.1 M.
Solve for (H^+).
thank u so much for ur help DrBob222!
