I wrote the dissociation or ionization in water for each of the following acids. I just want someone to check if they are right.

a) HC3H5O2(aq)<===> H^+(aq)+ C3H5O2^-(aq)

b) (CH3)2NH2^+(aq)<===> H^+(aq)+ (CH3)2NH(aq)

c) CH3COOH(aq)<===> H^+(aq)+ CH2COOH^-(aq)

d) H2PO4^-(aq)<===> H^+(aq)+ HPO4^2-

e) [Mn(H2O)6]^2+ <===> I don't know what to do with this one

Thanks

e) [Mn(H2O)6]^2+(aq)<===> H^+(aq)+ [Mn(H2O)5]5OH^+(aq)

a) HC3H5O2(aq)<===> H^+(aq)+ C3H5O2^-(aq)

This is an odd way to write the this

a) C3H5O2H(aq)<===> H^+(aq)+ C3H5O2^-(aq)

Your answer to a) means you have shown the wrong proton dissociating here.

c) CH3COOH(aq)<===> H^+(aq)+ CH2COOH^-(aq)

should be

c) CH3COOH(aq)<===> H^+(aq)+ CH3COO^-(aq)

[It is possible to remove the proton that you have shown but not in water]

I am not clear what they are after for e) either.

They may be simple be looking for

e) [Mn(H2O)6]^2+H2O<===> H^+(aq)+ [Mn(H2O)6]OH^+(aq)

Thanks, that helped a lot

a) HC3H5O2(aq) <===> H+(aq) + C3H5O2-(aq)

The dissociation or ionization of acetic acid (HC3H5O2) in water is correct. It breaks into H+ ions and C3H5O2- ions in the aqueous solution.

b) (CH3)2NH2+(aq) <===> H+(aq) + (CH3)2NH(aq)
The dissociation or ionization of dimethylamine (CH3)2NH2+ in water is correct. It forms H+ ions and (CH3)2NH or dimethylamine in the aqueous medium.

c) CH3COOH(aq) <===> H+(aq) + CH2COOH-(aq)
The dissociation or ionization of acetic acid (CH3COOH) in water is incorrect. Acetic acid dissociates into H+ ions and CH3COO- ions, not CH2COOH- ions. The correct equation should be:
CH3COOH(aq) <===> H+(aq) + CH3COO-(aq)

d) H2PO4-(aq) <===> H+(aq) + HPO42-
The dissociation or ionization of dihydrogen phosphate (H2PO4-) in water is correct. It forms H+ ions and HPO42- ions in the aqueous medium.

e) [Mn(H2O)6]^2+ <===> I don't know what to do with this one
The compound [Mn(H2O)6]^2+ is a coordination complex. It does not readily dissociate or ionize in water to produce H+ or OH- ions. Therefore, in this case, there is no simple dissociation or ionization equation.
