We have that the initial concentration  is mathematically given as

1 * {10}^{-11} M

Concentration

Generally the equation for the PH  is mathematically given as

[tex]pH = - log [ {H}^{+} ]\\\\given the H+ ions we discover the antilog of the pH\\\\11 = - log({H}^{+}) \\\\{H}^{+} = {10}^{ - 11}\\\\[/tex]

Therefore

1 * {10}^{-11} M
