Which of the following solutions would be expected to have the highest total molarity of all ions

A. 0.5M CrCl3

B. 0.5M NH4NO3

C. 0.5M BaBr2

D. 0.5M NaC2H3O2 E. 0.5M Li2CO3

Solutions

Expert Solution

Answer : A) 0.5 M CrCl3

A. 0.5M CrCl3

total molarity of ions = 0.5 + 3 x 0.5

= 2.0 M

B. 0.5M NH4NO3

total molarity of ions = 0.5 + 0.5

= 1.0 M

C. 0.5M BaBr2

total molarity of ions = 0.5 + 2 x 0.5

= 1.5 M

D. 0.5M NaC2H3O2

total molarity of ions = 0.5 + 0.5

= 1.0 M

E. 0.5M Li2CO3

total molarity of ions = 2 x 0.5 + 0.5

= 1.5 M
