Areaction has initial concentration of 0.230 m fe3+ and 0.410 m scn- at equilibrium, the concentration of fescn2+ is 0.150 m. a. what is the concentration of the fe3+ at equilibrium? b. what is the concentration of the scn- at equilibrium?

Answer :

a) The concentration of at equilibrium is 0.08 m.

b) The concentration of at equilibrium is 0.26 m.

Solution :

The equilibrium reaction is,

Initial concentration          0.230         0.410          0

At equilibrium              (0.230 - x)    (0.410 - x)       x

Given x = 0.150

Therefore,

The concentration of = 0.230 - x = 0.230 - 0.150 = 0.08

The concentration of = 0.410 - x = 0.410 - 0.150 = 0.26

Thus, the concentration of at equilibrium is 0.08 m.

The concentration of at equilibrium is 0.26 m.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
