Question

Explain why the conductivity of 0.059 M Ba(NO3)2(aq) is greater than that of 0.059 M KBr(aq). Choose all that apply.

-There is a higher concentration of free electrons in a solution of Ba(NO3)2 than there are in a solution of KBr.

-There is a higher concentration of Ba(NO3)2 than KBr.

-There are more ions generated by Ba(NO3)2 than generated by KBr when each is dissolved in water.

-The covalent bonds in Ba(NO3)2 increase its conductivity. KBr has no covalent bonds.

-There are no ionic bonds in KBr but there are ionic bond(s) in Ba(NO3)2.

-Some of the ions generated by Ba(NO3)2 carry more charge than some of the ions generated by KBr.

Answer:-

-There are more ions generated by Ba(NO3)2 than the generated by KBr when each is dissolved in water.

-Some of the ions generated by Ba(NO3)2 carry more charge than some of the ions generated by KBr.

Ba(NO3)2 -----------> Ba2+(aq) + 2NO3-(aq)

KBr ------> K+(aq) + Br-(aq)
