Question = Is C2Cl2polar or nonpolar ? The conjugate acid of a neutral base will have a charge of +1. Direct link to Dishita's post Yup, Ignore the use of any superscripts or subscripts in your answers. In general the stronger an acid is, the _____ its conjugate base will be. And on the other hand, when we have a weak acid C_2H_3O_2^- + H_2O ]rightleftharpoons HC_2H_3O_2 - OH^-;\;\;\;\textit{K}_b = 5.7\times 10^{-10}
