Question

read the following passage and find the two errors. then, choose the answer that corrects the errors. 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 0 - 16. 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 0 - 14. 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 0 - 16. 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 0 - 12. 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 0 - 16.

Explanation:

pH measures the concentration of $H^+$ ions, not $OH^-$ ions. The pH scale ranges from 0 - 14, not 0 - 16.

Answer:

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 0 - 14.
