Strong Acid, Strong base Titration
in mL) = (1.0 mmol)/(40 mL) = 0.025 M
Thus acid concentration, [H+] = 0.025 M
By definition, pH = -log [H+] = -log [0.025] = 1.60
Thus the pH after adding 15.0 mL of acid is 1.60
b) When 25.0 mL of base is added, that is enough base to get the

pH calculations for buffers, mixtures of acids and bases
You have probably learned that a "buffer" is a solution that is composed of a mixture of weak acid and weak base. The pH of the solution is determined by (a) the ratio of weak acid and weak base in the solution, and (b) the pKa of the weak acid.

Solutions of Acids, Bases, Salts, pH and Concentration
Label each of the following as an acid, base or salt, explaining your answer:
a. KOH: KOH will abstract a proton, this is correctly defined as Lewis base.
b. HCl : HCl will tend to donate a proton, this is correctly defined as Lewis acid
c.
