You're provided with a bottle labled [CoCl2.6H2O] = 0.056 M in 4.60 M HCl. You heat a small volume of the solution in a hot wate

sweet [91]

Answer: Equilibrium concentration of $[Cl^-]$ at $50^0C$ is 4.538 M

Explanation:

Initial concentration of $CoCl_2$ = 0.056 M

Initial concentration of $Cl^-$ = 4.60 M

The given balanced equilibrium reaction is,

$COCl_2+2Cl^-\rightleftharpoons [CoCl_4]^{2-}+6H_2O$

Initial conc. 0.056 M 4.60 M 0 M 0 M

At eqm. conc. (0.056-x) M (4.60-2x) M (x) M (6x) M

The expression for equilibrium constant for this reaction will be,

$K_c=\frac{[CoCl_4]^{2-}\times [H_2O]^6}{[CoCl_2]^2\times [Cl^-]^2}$

Given : equilibrium concentration of $[CoCl_4]^{2-}$ =x = 0.031 M

Concentration of $Cl^-$ = (4.60-2x) M = $(4.60-2\times 0.031)$ =4.538 M

Thus equilibrium concentration of $[Cl^-]$ at $50^0C$ is 4.538 M

Solid-solid homogeneous mixture give one example

likoan [24]

Example of solid - solid homogeneous mixture is copper metal - silver metal like coins and alloys. Homogeneous mixture is a mixture in which one of the substances often changes in form as in a solution of sugar in water. It contains variable proportions. Solution can contain two substances, three substances or more, in a single physical state. The component of a solution that is present in greatest quantity is usually called the solvent and all other components are called solutes.
