A solution has a pH of 3. What is the concentration of hydrogen ions in the solution?
A
10-3 M
B
10-10 M
C
103 M
D
1010 M
correct option: a
On the pH scale, each decrease in pH value by 1 represents a tenfold increase in the concentration of hydrogen ions. Since the pH is 3, the concentration of hydrogen ions is 10-3 M.
