Answer to Question #119137 in General Chemistry for Abigail Rouse

Question

A system at equilibrium, is represented by the following chemical equation:Fe³⁺₍ₐq₎ + SCN⁻₍ₐq₎ <--> Fe(SCN)²⁺₍ₐq₎. If the [Fe³⁺] = [SCN⁻] = 0.183 M and the K = 1.9 * 10², what is the [Fe(SCN)²⁺]?

Answer 1

Solution:

[Fe(SCN)²⁺]= [Fe³⁺]*[SCN⁻] *K

[Fe(SCN)²⁺] = 0.183*0.183*1.9*102= 6.36 M
