An acid-base titration consists of the controlled addition of a dissolved base to a dissolved acid (or the reverse). Acid and base react rapidly to neutralize each other. At the equivalence point, equivalents of reacting substances are equal. The pH during a titration changes every time with a drop of titrant added, but the rate of this change varies enormously. A titration curve, graph of pH as 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 `K_(a) and K_(b)` of acid and base
The suitable indicator for this titration will be:

A

bromo thymol blue

B

methyl orange

C

methyl red

D

all of these

In acid-base titration react rapidly to neutralise each other. Equivalence point is a point at which the acid and the base (or oxidising agent and reducing agent) have beem added in equivalent quantities. The end point in the point at which the titration stops. since the purpose of the indicator is to stop the titration close to the point at which the acid and base were added in equivalent quantities, it is important that the equivalent point and the end point be as close as must change colour at a pH close to that of a solution of the salt of the acid base. Singificantly, the pH changes most rapidly near the equivalent point. The exact shape of a titration curve depends on K_(a) and K_(b) of acid and base. The curve represents the titration of
