You're provided with a bottle labled [cocl2.6h2o] = 0.051 m in 4.60 m hcl. you heat a small volume of the solution in a hot water bath to 50 ∘c. if you determine that [cocl42-] = 0.031 m at 50 ∘c at equilibrium, what must be the equilibrium concentration of [cl-] at 50 ∘c?

Answer : The concentration of at equilibrium is 4.54 M

Explanation :

The equilibrium reaction will be:

Initial           0.051 M         4.60 M          0

At eqm.     (0.051-x) M     (4.60-2x) M    x

As we are given:

Concentration of at equilibrium = 0.031 M

That means,

x = 0.031 M

Concentration of at equilibrium = (4.60-2x) M = [4.60-2(0.031)] M = 4.54 M

Hence, the concentration of at equilibrium is 4.54 M

it is a good conductor

explanation:

it means there are 3 atoms of oxygen
