Chemical Properties Of Chloroform

The common reactions(chemical properties) shown by chloroform are listed below. –)Air Oxidation:- When Chloroform is left on open air in presence of sunlight,it gets decomposed to Carbonyl Chloride. 2CHCL3 + O2 –Sunlight–> COCL2 + HCl -The so formed Carbonyl Chloride is highly poisonous gas which is also used as a chemical weapon.To prevent quality loss … Read moreChemical Properties Of Chloroform

Electrochemical Equivalent (z), Chemical Equivalent (E), their Relations and Faraday’s Constant | Physics Grade 12

Electrochemical Equivalent (z) According to Faraday’s first law of electrolysis, m = z q or, z = m / q, where q = 1C, then z = m Hence, the electrochemical equivalent is the mass of ions deposited or liberated on an electrode during the electrolysis, where 1C of charge is passed through it. Chemical … Read moreElectrochemical Equivalent (z), Chemical Equivalent (E), their Relations and Faraday’s Constant | Physics Grade 12
