WebTo calculate the conducting electricity of an ionic solution, molar conductivity comes into play. The formula of molar conductivity is. Measurement of the conductivity of Ionic Solutions For the measurement of the molar conductivity of ionic solution, we take the help of a Wheatstone bridge. WebIn every ionic compound, the total number of positive charges of the cations equals the total number of negative charges of the anions. Thus, ionic compounds are electrically neutral overall, even though they contain positive and negative ions. We can use this observation to help us write the formula of an ionic compound.
