1. Guys,how can I know the position of equilibrium in a reaction eg.NH3+H2O==NH4+ + OH- and please explain how
2. Ask ur teacher if ur stuck
3. Kc values should give it, if it's large then it's to the right. Otherwise based on that, I think it would be to the right since Ammonia is pretty basic so it will accept protons from water.

oh damn that is well to the left pretty small KC... Were you expected to look that up? Otherwise how did you know without using the strength of the acid or base as an indication?

Ammonia is classified as a weak base.

Weak bases and weak acids typically dissociate less than 1% in aqueous solution.

As for the actual value, I just happened to remember it. It happens to be the same as the ka value of ethanoic acid.

Right because the Conjugate acid of ammonia is strong so it will dissociate back into NH3. My bad bruh
