What is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

The concentration of H + ions at pH 6.

The concentration of H + can be deduced by the formula pH = - log H + ==> H + = 10 ^ (- pH)

H + = 10^-6 mol / l.

But, it is necessary to be careful in this case the, to deduce the concentration of the acid, one can only deuire it only from H + since here there is the pH of the water which intervenes (which is not negligible in this case)

Concentration of -OH at pH 6.

The concentration of -OH can be calculated from pOH: pOH = 14 - pH = 14 - 6 = 8

-OH = 10 (pOH) = 10^-8 mol / l.

or directly: -OH = 10^-14 / 10^-6 = 10^-8 mol / l

Here we can notice that the higher the concentration of H + is inversely proportional to -OH. Acidity and alkalinity are two opposite terms. More acidity is strong, and the lower the alkalinity and vice versa.

Calculation of the ratio H + / -OH:

This ratio allows us to determine which of these two ions is the most abundant and its importance in the environment.

We have H + and -OH from previous data so

H + / -OH = 10^-6 / 10^-8 = 10^2 = 100.

Thanks to this report, we can see that there are 100 times more H + than -OH. and this is quite logical since the pH 6 remains an acidic pH (less than 7) but which is still close to the neutrality.
