Question
Air pollutants frequently cause acid rain. A
measure of the acidity is pH, which ranges between
1 and 14. Pure water is neutral and has a pH of 7.
Acidic solutions have a pH less than 7, whereas alka-
line solutions have a pH greater than 7. A pH value
can be computed by pH = −logx, where x repre-
sents the hydrogen ion concentration in moles per
liter. In rural areas of Europe, rainwater typically
−4.7
has x = 10 . ( Source: G. Howells, Acid Rain and
Acid Water.)
(a) Find its pH.
(b) Seawater has a pH of 8.2. How many times greater is the hydrogen ion concentration in rainwater from rural Europe than in seawater?
