Answer #1

The dissociation of weak electrolyte is given by AB(aq) A+(aq) + B-(aq)

Since FORMIC ACID, HCOOH is weak electrolyte and there exists a equilibrium between the dissociate ions H+(aq) and HCOO-(aq) and undissociated acid, HCCOH

The disscoiation weak acid, HCOOH is given by

                HCOOH(aq)   HCOO-(aq) + H+(aq)

The solute particles are present in an aqueous solution of this compound HCOOH(aq), HCOO-(aq) , H+(aq)
