Here are my 2 equations. Please tell me whether the reactants or products will be favored at equilibrium. I *think* I know the answers, but I want to double check. Thank you!!

1) HF + OH- ⇌ F- + H2O

2) HCN + OH- ⇌ CN- + H2O

what do you think and why

Remember that side of the reaction is favoured in equilibrium which has weaker acid and weaker base..

On basis of this heres the first one

(1) HF + OH-  <->  F- + H2O

HF is stronger acid than H2O
OH- is stronger base than F-

So the equilibrium favours the products side here

Now can you try the second one?

[hiswifetheirmom]

HCN + OH- <---> CN- + H2O

Given the reasoning I would say that in this equation, the products would be more favorable because OH- is the stronger base and HCN is the stronger acid.  Am I right??

Yes

Yay!!  Thanks so much for your help.  I feel like I truly understand now.  I appreciate it.
