Question

Which species is a conjugate acid of OH-?

Answer 1

Water.

Step-by-step explanation:

Hello,

In this case, you are referring to the dissociation or formation of water at the equilibrium, that is:

`H^++OH^-<-->H_2O`

In such a way, the water is the conjugate acid of the hydroxile ion as long as it gains a proton.

Best regards.

Answer 2

It seems that you have missed the necessary options for this answer, but anyway, the answer for this would be H20. The specie that is a conjugate acid of OH- is H20. H20 is the conjugate acid and OH- is the conjugate base. Hope this answers your question. Have a great day!
