... A milliequivalent is equal to the number of univalent counter ions (H+ or OH) which will be needed to react with one molecule of the substance When an atom has a valence of one ( e.g. Na+, K+, CI, etc.) a mEq of that ion is equal to the atomic weight of the atom in milligrams. For example, one mEq o ...
