Question

$\underset{base}{H_{2}O\left(l\right)}+\underset{\left(x\right)}{H_{2}O}\left(l\right)\leftrightharpoons H_3{O}^{+}(aq.)+\underset{\left(y\right)}{O{H}^{-}}(aq.)$

Here (x) and (y) refer to:

• A. Base and conjugate acid
• B. Acid and conjugate base
• C. Base and conjugate base
• D. Acid and conjugate acid

Answer 1

The correct option is B Acid and conjugate base

$\underset{\left(base\right)}{H_{2}O\left(l\right)}+\underset{\left(acid\right)}{H_{2}O}\left(l\right)\leftrightharpoons H_3{O}^{+}\left(aq\right)+\underset{\left(\text{conjugate base}\right)}{O{H}^{-}}\left(aq\right)$
