In case of reversible reactions , if the products are allowed to stand undisturbed then they start the backward reaction. This process happens until we get 1:1 of products and reactants. The whole phenomenon is called chemical equilibrium.

In case of molarity the volume of solvent is taken but in case of molality the mass of solvent is taken. With change in temprature the volume can increase or decrease but the mass remains same . So molality is preferred over the molarity. The main reason for this is that the molarity is the

Au is the symbol used for gold metal. This symbol is taken from the Latin language and in Latin language gold is known as Aurum.

In case of Nitrogen molecule, the two atoms of Nitrogen are joined with each other by triple bond. And to break this bond we require large amount of energy. This makes the molecule nearly inert. As shown below.

In case of halogens the electrons present in outer shell absorb the energy in visible region and get excited to higher level . During these transitions the emissions are in visible region thus these compounds appear coloured.

Emulsion is the type of colliodal mixture :- In which the dispersion medium is oil and dispersed phase is water. for example ‘Butter’ In which the dispersion medium is water and dispersed phase is oil. for example ‘milk’ . Applications or examples of emulsification In case of cleaning action of soap, the soap solution acts

On the application of electric field , the colloidal particles move towards the oppositely charged electrode. on reaching at the electrode , the particles get discharged and they coagulate there. this process is also known as the Electrophoresis.

Soaps and detergents are associated colloids.

In case of chemisorption there is a partial bond like interaction between the adsorbate and adsorbent . During such an interaction the higher amount of energy is required because bond formation and breaking will require more energy. but on the other hand in case of physisorption the adsorbate and adsorbent particles are simply held together

In case of As2S3 the colloidal particles scatter the light passing through solution and show Tyndall effect.

In case of enzyme catalyst , they have specific sites for the attachment of substrate or the reactant. Any other molecule or substrate can not join with the catalyst. here is a diagram to show the phenomenon.

Multimolecular colloids :- These kind of colloids are formed when many small molecules or atoms are forced to aggregate in the dispersion medium. Thses colliods are lyophobic (solvent hating) in nature. for example gold solution Macromolecular colloids :- These are colloids which are formed of such a molecules which are enough large to have colloidal

the depression in freezing point (which is a colligative property) depends upon the number of solute particles present in the solution. when sodium chloride is mixed in the water it dissociates into Na+ and Cl– ions thus this increases the number of particles . but glucose don’t dissociate and its freezing point is higher than

The elevation in boiling point depends upon the number of solute particles present in the solution. when sodium chloride is mixed in the water it dissociates into Na+ and Cl– ions thus this increases the number of particles . but glucose don’t dissociate and its boiling point is lower than Sodium chloride.
