JEE MAIN - Chemistry (2005 - No. 8)
What is the conjugate base of OH-?
O2
H2O
O-
O-2
Explication
Conjugate acid-base pair differ by only one proton.
$$O{H^ - } \to {H^ + } + {O^2}^ - \,\,$$ Conjugate base of $$O{H^ - }$$ is $${O^{2 - }}$$
$$O{H^ - } \to {H^ + } + {O^2}^ - \,\,$$ Conjugate base of $$O{H^ - }$$ is $${O^{2 - }}$$
