1.

Consider the statement ‘Specific conductance increases on dilution’.1. Is it true? 2. What is your opinion about it? Justify. 3. Dene specific conductance and give its equation.

Answer»

1. No.

2. This is because, the number of ions per unit volume that carry the current in a solution decreases on dilution.

3. Specific conductance/Conductivity of a conductor is the conductance offered by the conductor of unit length and unit area of cross section.

k = \(\frac{l}{RA}=\frac{1}{R}\,\times\,\frac{l}{A}\) is the cell constant.
