which ph indicates an alkaline solution.
An alkaline solution is a mixture of base solids dissolved in water. The potential of hydrogen, also known as the pH scale, measures the alkalinity or acidity level of a solution. The scale ranges from zero to 14. The midpoint 7 represents a neutral pH. A neutral solution is neither an acid nor alkaline. pH levels below 7 indicate an acidic solution, and numbers above 7 indicate an alkaline solution. The pH is a measurement of intensity, not capacity and any movement within the pH scale indicates a tenfold increase in the acid or alkaline measurement. Amophoteric (of a compound, especially a metal oxide or hydroxide) able to react both as a base and as an acid.
