Question
Equal volume of 0.1M NaCl and 0.1M FeCl2 are mixed with no change in volume due to mixing. Which of the following will be true for the final solution. (No precipitation occurs). Assume complete dissociation of salts and neglect any hydrolysis.
Options
A.[Na+] = 0.05 M
B.[Fe2+] = 0.05M
C.[Cl-] = 0.3M
D.[Cl-] = 0.15M
Solution
Vml 0.1 M NaCl
Vml 0.1 M FeCl2
[Na+] =
= 0.05 M
[Fe2+] =
= 0.05 M
[Cl-] =
= 0.15 M
Vml 0.1 M FeCl2
[Na+] =
= 0.05 M[Fe2+] =
= 0.05 M [Cl-] =
= 0.15 MCreate a free account to view solution
