Calculate the concentration of an aqueous solution of naoh that has a ph of 11.98.

0.001 mol/L. The concentration of an aqueous solution of NaOH with a pH

of 11 is 0.001 mol/L

Step 1. Calculate the pOH of the solution

pOH = 14.00 - pH = 14.00 - 11 = 3

Step 2. Calculate the concentration of NaOH

[NaOH] = [OH^ (-) ] = 10^ (-pOH) mol/L = 10^ (-3) mol/L = 0.001 mol/L
