The best indicator for titrating HCl against NH_(4)OH is :

The extent to which hydrolysis proceeds is expressed as degree of hydrolysis and is defined as fraction of ne mole of the salt that is hydrolysed when equilibrium has been attained . The nature of solution also depends upon the extent upto which the salt has been hydrolysed . Degree of hydrolysis of a salt ofdepends upon concentration of salt at a particular temperature and varies inversely . Consequently , nature of the solution whether acidic or alkaline can be determined . pH of the solution of salt of weak acid and strong base or weak base and strong acid depends upon its concentration . So by varying the concentration of salts their pH could be adjusted . For strong base and weak acid litration , the [H_(3)O^(+)] at equivalence point will be
