Acidity Calculator
Definition: Acidity is the quantitative capacity of water to react with a strong base to a specified pH endpoint. It is commonly expressed as mg/L as CaCO₃.
Acidity (mg/L as CaCO₃) =
(A × N × 50,000) / V
Where A is the volume of standard alkali used in mL, N is the normality of the alkali, and V is the sample volume in mL.
