What is Hardy-Schulze rule ?

Hardy-Schulze rule It has two postulates (i) The ions which carry charge opposite to the particles of sol are more effective in causing the coagulation of the solution. (ii) Coagulating power of an electrolyte is directly proportional to the fourth power of the valency of the ions causing coagulation.

What are Multimolecular and Macromolecular colloids?

Multimolecular colloids are formed when the molecules of dispersed phase aggregate to make a molecule which is having the size between 1nm to 1000nm. The point to note here is , the particles of colloidal solution were of molecular size which joined to make Multimolecular system. Macromolecular colloids are the substances in which the size of particles is 1nm to […]

What are isoelectric species? And What determines the difference in the size of atoms or ions if they are isoelectronic ?

Isoelectric species are simply the atoms or ions that have same number of electrons. For example:- Na+ , Ne , F- , O¬≤- , Mg¬≤+ And their size depends upon the effective nuclear charge , in case of cations the number of protons is higher than that of electrons thus their size is smaller than that of neutral atom. For […]
