In a neutral solution, the concentration of H+ ions is 1 x 10^-7 moles per liter. This means the solution has a pH of 7.
To evaluate the ratio MH plus pH 3 divided by MH plus pH 7, first determine the molar concentration of each species at pH 3 and pH 7 using the Henderson-Hasselbalch equation. Then calculate the ratio of the concentrations of MH at pH 3 to pH 7, and divide this by the ratio of pH 3 to pH 7.
The pH is 6,15.
7 pounds plus 8 pounds equals 15 pounds.
Seven tenths is 7/10, or seventy percent of anything.
