To calculate the pH of a weak acid, it is important to note that pH has no units, thus it is required to define it with H+ ion concentration.
A strong acid is one that readily gives up its protons, and does so even when the ambient pH is low, which means there are already a lot of protons floating around. Weak acids do not give up their protons so easily, becoming dissociated to a meaningful extent only when pH is closer to...

In chemistry, a "buffer" is a solution you add to another solution in order to balance its pH, its relative acidity or its alkalinity. You make a buffer using a "weak" acid or base and its "conjugate" base or acid, respectively. To determine a buffer's p

Salt consist of protonated nicotine (weak conjugate acid of nicotine) and Cl-(base so weak, that its presence doesn't change pH). You have to find out Ka of protonated nicotine (hint: pKa + pKb = .), then you have just a solution of weak acid. ...
