Which of the following statements are correct? 1. The oxidising power of halogens decreases from chlorine to iodine 2. Equivalent conductance increase with dilution for an electrolyte solution while its specific conductance decreases 3. For a weak electrolyte, the plot of lamdam against sqrt(c) is nearly linear. 4. Ametal M for which E^(@) for the half reaction Mn^(+)+"ne"(-)to M is very negative will be a good reducing agent

Assertion: Specific conductance decreases with dilution whereas equivalent conductance increases. Reason: On dilution, number of ions per millilitre decreases but total number of ions increases considerably.

Why does the conductivity of a solution decreases with dilution?

Assertion: The conductivity of an electrolyte is very low is compared to a metal at room temperature. Reason : The number density of free ions in electrolyte is much smaller as compared to number density of free electrons in metals. Further, ions drift much more slowly, being heavier.

Assertion : The Van't Hoff factor for a weak electrolyte in water is dependent of its concentration. Reason : The degree of dissociation of a weak electrolyte increases on dilution.

The variation of equivalent conductance of weak electrolyte with concentration is correctly shown in figure:

The effect of temperature increases, : electrolytic conduction decreases , Metallic conduction increases, metallic conduction decreases, Electrolytic conduction increases, metallic conduction decreases, Both electrolytic and metallic conduction decreases, Both electrolytic and metalllic conduction increases

Assertion: The ratio of specific conductivity to the observed conductance does not depend upon the concentration of the solution taken in the conductivity cell. Reason: Specific conductivity decreases with dilution whereas observed conductance-increases with dilution.

Assertion : Molar conductivity increases with decrease in concentration. Reason:Conductivity always decreases with decrease in concentration.

Assertion : Fluorine combines with sulphurto form SF_6 but no other halogen forms hexahalide wth sulphur. Reason The reactivity of halogens increases as the atomic number increases.
