Question

Explain why the conductivity of 0.073 M Ba(NO3)2(aq) is greater than that of 0.073 M KBr(aq).

A) The total ion concentration of the Ba(NO3)2 is greater than the KBr. In addition, some or all of the ions in Ba(NO3)2 have higher charge than those of KBr. Both of these factors increase the conductivity of the Ba(NO3)2 solution.

B) Electrolytes with a NO3– anion will always have a higher conductivity when compared to any other electrolyte. Thus the Ba(NO3)2 will always have a higher conductivity than KBr as long as they are at the same concentration.

C)Conductivity increases when electrolytes react with water. Ba(NO3)2 reacts much more readily with the water than KBr, thus the greater reactivity of Ba(NO3)2 will lead to a much greater conductivity in solution.

D) The KBr is a weak electrolyte while the Ba(NO3)2 is a strong electrolyte. Thus the Ba(NO3)2 fully ionizes in solution and will have a higher conductivity than the KBr.

Answer 1

answer :

A) The total ion concentration of the Ba(NO3)2 is greater than the KBr. In addition, some or all of the ions in Ba(NO3)2 have higher charge than those of KBr. Both of these factors increase the conductivity of the Ba(NO3)2 solution.

explanation:

Ba(NO3)2 , number of ions = 3 (Ba+2 , 2NO3-)

KBr number of ions = 2 (K+ , Br-)

number of ions increases conductivity increases it is common point . and also charge increases condctivity increases . Ba+2 has charge in first compound so Ba(NO3)2 is ultimately greater conductivity than KBr
