Question = Is C2Cl4polar or nonpolar ? can combine with OH-, this will go with OH-, and I'll get NH4OH and this is going to be a base. NaOH). So the strong parent is the acid. The number 1.12 has 3 significant figures, and the answer must therefore be quoted to 3 significant figures. It becomes basic in nature. Since there is no transfer of hydrogen atoms here, it is clear that this is a Lewis acid-base reaction. 1) Is the solution of C5H5NHClO4 acidic, basic or Lewis acid {/eq} and acetic acid{eq}\rm \left( {C{H_3}COOH} \right) b) Neutral because there is no hydrolysis.
