how is a solution of an inequality like a solution of an equation

Preparation of Colloidal Sols - For the preparation of lyophilic and lyophobic sols different methods are us..

Since lyophilic sols are quite stable, they can be easily prepared by shaking the lyophilic substance with the dispersion medium. Examples are: Colloidal sols of gum, starch, gelatine and egg album..

The colloidal solutions prepared by various methods usually contain electrolytes and other soluble substances as impurities. These impurities if not removed can destabilize the sols..

Heterogenous nature - Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Preparation of Lyophilic Sols Since lyophilic sols are quite stable, they can be easily prepared by shaking the lyophilic substance with the dispersion medium. Examples are: Colloidal sols of gum, starch, gelatine and egg albumi..

The method used to purify impurities that are easily oxidizable is cupellation. Silver is refined by this method. The impure metal is fused in small boat shaped dishes made of bone ash called as cupels. The cupels are heated in a suitable furnace by a blast of air blown over them. The impurity ..

(i) Boron's atomic number is 5. Its electronic configuration is 1s 2 2s 2 2p 1 . Hence it can lose 3 electrons from the second orbit to form bonds, as the new configuration is more stable. (ii) Boron reacts with strong oxidizing acids like concentrated sulphuric or concentrated nitric ..

A double bond between carbon-carbon atoms (C=C) consists of a sp 2 -sp 2 s bond and a p bond. These bonds are formed between unhybridized '2p' orbitals of each C atom at right angle to the plane of sigma bond. Since the p bond prevents the free rotation about the carbon-carbon axis, a di-sub..

The law of conservation of energy states that whenever one form of energy is lost, an equivalent amount of energy in another form appears, i.e. the energy is always conserved. If it were so, then there should have been no energy crisis? As our experience is altogether different, the explanation fo..

The set of ordered pairs (x,y), which satisfy the given inequation, is called the solution set of the inequations..
