• A pH of 7 is considered neutral

• Substances with pH below 7 are acidic, above 7 are alkaline

• pH is important in various industries like food, pharmaceuticals, and environmental monitoring

Normality is a measure of concentration in chemistry, expressed as the number of equivalents of a solute per liter of solution.

• It is calculated by dividing the number of equivalents of solute by the volume of solution in liters.

• Normality is often used in acid-base titrations and redox react...read more
