Question
An acid-base titration consists of the controlled addition of a dissolved base to a dissolved acid (or the reverse). Acid-base react rapidly to neutralize each other. At the equivalence point, enough titrant, the solution being added, has gone into make the chemical amounts of the acid and base' exactly equal. The pH of a titration changes every time a drop of titrant is added, but the rate of this change varies enormously. A titration curve, graph of pH tis a function of the volume of titrant, displays in detail how the pH changes over the course of an acid-base titration. Significantly, the pH changes most rapidly near the equivalence point. The exact shape of a titration curve depends on the 
and 
acid and base
Which of the titrations could it represent?
- HCl by KOH
- RbOH by HBr
- HCl by NaOH
The correct answer is: RbOH by HBr

When a salt reacts with water to form acidic or basic solution, the process is called hydrolysis. The pH of salt solution can be calculated using the following relations
(for salt of weak acid and strong base.)
(for salt of weak base and strong acid.)
(for salt of weak acid and weak base.)
where, 'C' represents the concentration of salt.
When a weak acid or a weak base is not completely neutralized by strong base or strong acid respectively, then formation of buffer takes place. The pH of buffer solution can be calculated using the following relation
When 50 mL of 0.1 M NaOH is added to 50 mL of 0.05 M 
solution. The pH of the solution is:
