Which of the following solutions of HCN will have the greatest percent dissociation? Weak electrolytes only partially break into ions in water. This is the most wide-ranging of the three (i.e. Is there any chart which tells how strong or weak a base or acid is? Acid dissociation is represented by the general equation HA + H2O (l) H3O+ (aq) + A- (aq). {/eq} is described as a salt of weak acid that is acetic acid {eq}\left( {C{H_3}COOH} \right) Is ammonium acetate (NH4C2H3O2) acidic, basic, or neutral in pH?
