Question

part a
the ph scale ______.

• is based on the salinity of a solution
• is based on the concentration of hydrogen ions in a solution
• is linear
• ranges from 1 to 7

Explanation:

The pH scale quantifies the acidity/alkalinity of a solution, defined by the negative logarithm of the hydrogen ion concentration. Salinity refers to salt content, which is unrelated to pH. The scale is logarithmic, not linear, and ranges from 0 to 14, not 1 to 7.

Answer:

is based on the concentration of hydrogen ions in a solution
