tigry1 [53]

Answer:

See explanation

Explanation:

Conductivity of a solution refers to its ability to conduct electricity. It is a measure of how much the solution can conduct electricity.

Looking at the reaction; Ba(OH)2(aq) + H2SO4(aq) ---------->BaSO4(s) + 2H2O(l)

We can see that the concentration of ions in solution decreases from left to right. As the concentration of ions decreases, the conductivity of the solution decreases accordingly since conductivity of solution depends on the concentration of ions in solution.

Also, the solution appears cloudy as the reaction progresses due to the formation of BaSO4(s).
