Question

Arrange the three NaCl solutions used in increasing order of conductivity (lowest to highest).

How does molarity (M, or concentration of ions present) affect conductivity? Defend your answer.

Answer 1

a) the three NaCl solutions used in increasing order of conductivity

0.01M NaCl < 0.02M NaCl < 0.03M NaCl.

b)Conductivity is an index of how easy it is for electricity to flow. In water, it is the ions that pass electricity from one to the next. This means that the more Na⁺ and Cl^-contained in water the more electricity is carried, and the higher the conductivity. In other words, higher concentration of Salt , number of ions in the solution is higher. More the number of ions, it conducts more number of current inturn it increases the conductivity of the solution.
