H3O and OH

Postby KDang_1D » Mon Jan 06, 2020 3:58 pm

Regarding the Chemical Equilibrium Pt 1B Pre-Assessment, for reactions that involve liquid water as a product and H3O+(aq) or OH-(aq) as a product, are the H3O/OH included in the K calculation?

I believe they would be, since only reactants and products that are in the solid and liquid phases don't contribute to equilibrium rate constants.

The only things that are included in the equilibrium equation are compounds/molecules that are either aqueous or gases. Therefore they would be included in the equation.

Yes, as these solutions are aqueous they would. Water (H2O(l)) would not be included because it is the solvent.

Anything gas or aqueous should be included. Solvents (l) or solids will not be including in calculating Kc/Kp.

I think they should be included, as they are not a solid, liquid, or solvent.
