The electrical conductance of a solution of Ba(OH)2 slowly decreases upon the addition of HSO4 to a minimum, and then slowly increases. The best theoretical explanation of this is (A) The Ba(OH)2 solution becomes more dilute since its volume is increased by adding the H2SO4 solution. (B)lons are removed from the solution by the formation of water and insoluble BaSO4. (C)The interionic attraction effect is increased by adding the H2SO4 (D) An electric lamp placed in a circuit in series with the solution becomes dim as the H2SO4 is added and then becomes bright again. (E) An indicator placed in the solution changes color. could you explain which option you get and why?
