which of the following is true for the following reaction HC2H3O2(aq) + KOH(aq) -->?

Question

a) C2H3O2 -(aq) is a product

b) When balanced the coefficient of KOH(aq) is 3

c) Only ions appear in the net ionic equation

d) H+(aq) does not appear in the net ionic equation

e) K+(aq) appears in the net ionic equation

Answer 1

===> K+(aq) + C2H3O2-(aq) + H2O

a) Yes (Look!)

b) No; it is 1

c) No; H2O appears, and it is an unionized substance (you have to forget the 10^-7M H+ and OH- ions)

d) This is a tough one! HC2H3O2 is a part of the equation. But HC2H3O2 is only 4x10^-4M ionized into H+ So does that amount of H+ count? Or do you say that HC2H3O2 is an essentially unionized substance, so there is no H+? Come back and tell us what the Arbiter of Fashion says!

e) No
