An indicator is a weak acid and `pH` range of its colour is `3` to `5`. If the neutral point of the indicator lies in the centre of the `[H^(+)]` corresponding to given `pH` range, then `pH` at the equivalence point is

An indicator is a weak acid and the pH range of its colour is 3.1 to 4.5. If the neutral point of the indictor lies in the center of the hydrogen ion concentrations corresponding to the given pH range, calculate the ionization constant of the indicator.

The pH range of acids is-
