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. (2 points)
O pH is a measure of the concentration of Htions in a solution of an acid or base. The pH plots the
concentration of solutions in a range from 0-14.
O pH is a measure of the concentration of Htions in a solution of an acid or base. The basic scale plots the
concentration of solutions in a range from 0-16.
O 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.
O pH is a measure of the concentration of OH ions in a solution of an acid or base. The acid scale plots the
