Number of equivalents of SO 4 2 − present in the solution containing 5 .0 mEq SO 4 2 − ions has to be determined. Concept-Introduction: Body fluids have small amounts of different type electrolytes and its concentration is measured in equivalents or milliequivalents per liter. An Equivalent ( E q ) of an ion is the molar amount of a certain ion required for supplying one mole of negative or positive charge. Few examples for the relationship between number of equivalent and charge of an ion is given below, 1 mole = 1 equivalent ( For ions with charge 1+ or 1 − ) 1 mole = 2 equivalent ( For ions with charge 2+ or 2 − ) 1 mole = 3 equivalent ( For ions with charge 3+ or 3 − ) Unit Conversion: 1 Eq = 10 3 mEq
