# What is a gas that dissolves readily in water to produce a solution with a pH of about 11?

Sep 14, 2016

Possibly ammonia, $N {H}_{3}$, which is extremely soluble in water.

#### Explanation:

Ammonia undergoes the following acid base equlibrium in water:

$N {H}_{3} \left(a q\right) + {H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s N {H}_{4}^{+} + H {O}^{-}$

$p {K}_{b} = 4.75$.

Look for ammonia fountains on youtube; they are spectacular reactions.
