Question

PH is a measure of the concentration of OH ions in a solution of an acid or base. The pH scale plots the concentration of solutions in a range from 016.

a) pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots the concentration of solutions in a range from 014.
b) pH is a measure of the concentration of H+ ions in a solution of an acid or base. The basic scale plots the concentration of solutions in a range from 016.
c) pH is a measure of the concentration of OH- ions in a solution of water. The pH scale plots the concentration of solutions in a range from 012.
d) pH is a measure of the concentration of OH- ions in a solution of an acid or base. The acid scale plots the concentration of solutions in a range from 016.

Answer 1

The pH scale measures the concentration of hydrogen ions in a solution and ranges from 0 to 14. Acids lower pH by providing H+ ions, while bases raise pH by providing OH- ions.

Step-by-step explanation:

The pH scale is a measure of the concentration of hydrogen ions (H+) in a solution of an acid or base. It ranges from 0 to 14, with 0 being the most acidic and 14 being the most basic. A pH value of 7 is considered neutral.

The pH scale is logarithmic, which means that a change of one unit on the scale represents a tenfold change in the concentration of hydrogen ions. For example, a solution with a pH of 4 is ten times more acidic than a solution with a pH of 5.

Acids provide hydrogen ions (H+) and lower pH, while bases provide hydroxide ions (OH-) and raise pH. Strong acids, like hydrochloric acid, readily donate H+ ions, while strong bases, like sodium hydroxide, readily donate OH- ions.
