  1. The molecular weighs of water is 18.015 and 1L of pure water at 250C weighs about 1000g. Therefore, the molar concentration of water is 1000/18.015 = 55.509 mol L-1. One molecule of water in every 107 molecule dissociate into H+ and OH- ions. However, this slight dissociation of water is very essential for many of […]
  2. Ion exchange is meant the reversible process by which cations and anions are exchanged between solid and liquid phases, and between solid phases if in close contact with each other. Other terms to be used in this aspect are ion adsorption, meaning an increase in concentration or an accumulation of an ion species on a […]
