Equivalent weight of potassium
WebTherefore, the number of equivalents is 2. The equivalent weight of Ba(OH)2 is 189.4 2 = 94.7 g equivalent. H3PO4: The molecular weight of H3PO4 is 98 g/mol. H3PO4 donates three replaceable hydrogen ions (H+) per molecule. Therefore, the number of equivalents is 3. The equivalent weight of H3PO4 is 98 3 = 32.67 g equivalent. WebNormality is the gram equivalent weight of a substance per liter of solution. It can also be defined as "Normality: N = moles of reactive units per liter (equivalents per liter)" ... And potassium and chloride, they all have 1 equivalent. So that's what equivalents mean in terms of the moles needed to balance out a charge on the opposite side.
