Which of the two aqueous solutions will be a better conductor of electricity in the following examples? Explain why in each case.

a) 1.0M NaCl vs. 0.010 M Nacl

b) 0.10 M NaCl vs. 0.10 M Al2 (SO4) 3 (assume complete dissociation of both salts).

c) 1.0 mole of NaCl added to water vs. 1.0 mole of pbCl2 added to water (hint: remember the solubility rules).

A) The solution with a concentration of 1.0 M NaCl will be a better conductor of electricity since it has a higher number of electrolytes

b) The 0.10 M Al2 (SO4) 3 will be a better conductor since more ions are formed per mole of the salt dissociated

c) 1.0 mol of NaCl in water because NaCl is very soluble in water
