Ionic Strength of Uni-Bivalent Electrolyte Solution

Follow our step by step solution on how to calculate Ionic Strength of Uni-Bivalent Electrolyte?

FIRST Step Consider the formula

I = (\frac{1}{2}) \cdot (m + \cdot ({(Z +)}^{2}) + (2 \cdot m - \cdot ({(Z -)}^{2})))

Next Step Substitute values of Variables

∴

I = (\frac{1}{2}) \cdot (0.01mol/kg \cdot ({(2)}^{2}) + (2 \cdot 0.002mol/kg \cdot ({(2)}^{2})))

Next Step Prepare to Evaluate

∴

I = (\frac{1}{2}) \cdot (0.01 \cdot ({(2)}^{2}) + (2 \cdot 0.002 \cdot ({(2)}^{2})))

LAST Step Evaluate

∴

I = 0.028mol/kg
