(a) weak base
(b) strong base
(c) weak acid
(d) strong acid

1. the ph is a measure of oxygen ions (o+).

true
false

Explanation:

1. The pH scale ranges from 0 - 14. A pH near 1 indicates a high concentration of hydrogen ions ($H^+$), which is characteristic of a strong acid.
2. A pH near 14 indicates a low concentration of hydrogen ions and a high concentration of hydroxide ions ($OH^-$), which is characteristic of a strong base.
3. The pH is a measure of the hydrogen - ion concentration ($[H^+]$), not oxygen ions.

Answer:

1. D. Strong acid
2. B. Strong base
3. False
