so in the equation
2HC2H3O2 + NaCO3 --> . . . . . . . .
would you separate the 2HC2H3O2 into cations and anions?? since it "partially" ionizes?
also, isn't it true that ANY ionic compound that contains acetate is soluble in water? So if the answer is 'no' for HC2H3O2, whats the exception?

yes it partially ionize in water......
thats why it is a weak acid

Acetic acid is a vulnerable acid so it does no longer dissociate thoroughly like good acids. even whether, once you're taking over the undertaking of the dissociation of acetic acid under commonly used circumstances then it extremely is going to be exothermic. Delta G = Delta H - T Delta S by utilising potential of actuality the reaction is spontaneous, Delta G is unfavorable. Delta S is smart by utilising potential of actuality it is going from HCOOH to COOH- AND H+ => enhance in entropy. as a consequence, Delta H might prefer to be unfavorable meaning exothermic.

Acetic acid, CH3COOH, is a weak acid in that it partially ionizes in water. This behavior is characterized by the acid equilibrium constant Ka, which for acetic acid is about 1.8x10-5.
