WebThe acidity of alcohols is comparable to that of water. Concept Introduction: Chemical reaction is the procedure to transform the chemical substance in the new substance. During this procedure sometimes, acid is involved which is the substance which could either accept electron pairs or donate protons in the reactions. WebMost acids, however, are able to hold on to their protons more tightly, so only a small fraction of the acid is dissociated. Thus hydrocyanic acid, HCN, is a weak acid in water because the proton is able to share the lone pair electrons of the cyanide ion CN – more effectively than it can with those of H 2 O, so the reaction. HCN + H 2 O → ...
