How acid, base , and pH relates
It is a substance(chemical or natural) which changes colour in the presence of an acid or base.
The strength of a weak acid is inversely related to the strength of its conjugate base. If an acid is weak, its conjugate base will be stronger because the weaker the acid, the more easily it will give up its proton to form the conjugate base. Conversely, a stronger acid will have a weaker conjugate base.

Indicator.See related links below.
In a chemical reaction, a weak acid and its conjugate base are related as a pair. When the weak acid donates a proton, it forms its conjugate base. The conjugate base can then accept a proton to reform the weak acid. They exist in equilibrium, with the weak acid and its conjugate base acting as partners in the reaction.
An acid base pair which differ from each other by a single proton(H+ ion) is called a conjugate pair. Eg. Acid Base HCl Cl- NH3 NH4+ H2O H3O+
An acid, according to the Related Link on the bottom,it has a pH of 0 which is acidic
Strong acids and bases dissociate completely in water. Strong acids produce a pH of less than 3 and form weak conjugate bases. Strong bases produce a pH greater than 10 and form a weak conjugate acid.
Salts are the products of a reaction between an acid and a base.
Acid base pairs differing ONE proton (H+) are called conjugate acid-base pair.Examples:H3O+ and H2OH2O and OH-NH4+ and NH3HBr and Br-HNO2 and NO2-H2SO4 and HSO4-HSO4- and SO42-HOCl and OCl-(In order of 'acid and base' respectively)
