    If u have understood the term adsorption u would easily understand this year sorption... Basically adsorption is a process in which one substance gets accumulated on the surface of another substance ..nad on the other hand the term adsorption is process of removing that acculated substance .....so when these two processes happen simultaneously.... The basic term is used and is called as sorption....... 1.the substance which gets accumulated on the surface of another substance.. - adsorbate 2. The substance on the surface of which another substance has accumulated - absorbent

    Gold Number is a term used in colloidal chemistry. It is defined as the minimum amount of protective colloid in milligrams which prevents a color change from red to violet of 10ml gold sol by the addition of 1 ml of 10% NaCl solution.

    It may be defined as 'least quantity of protective colloid in milligrams, which is just sufficient to prevent the coagulation of 10 ml of standard gold sol (containing 0.0053% gold) by the rapid addition of 1 ml of 10% NaCl solution. Thus small the gold number, the greater is protective power of lyophilic colloid.

    In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth.

    For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth. This happens because NaCN reacts with ZnS to form Na2[Zn(CN)4].

    4 NaCN + ZnS → Na2[Zn(CN)4] + Na2S
