Find ph from ka and molarity

WebA solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base. Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated. WebExample: Calculate the Ka of 2M hypochlorus acid (HCIO) if its pH is 5. Then, we use the ICE table to find the concentration of the products. Therefore, x is 1 x 10^-5. Therefore, the Ka of the hypochlorus acid is 5.0 x 10^-10.
