Normality class 12
WebNormality = Molarity x Basicity. To know the value for basicity, count the number of H + ions an acid molecule can give. For bases the normality can be calculated with the following formula: Normality = Molarity x Acidity. To know the value for acidity, count the number of OH – ions a base molecule can give.
