Consider the insoluble compound cobalt(II) hydroxide , Co(OH)2 . The cobalt(II) ion also forms a complex with ammonia . Write a
Nuetrik [128]

Answer:

4.56×10^-10

Explanation:

Co(OH)2(s)<------->Co^2+(aq) + 2OH^-(aq)

Co^2+(aq) + 6NH3(aq) ---------->[Co(NH3)6]^2+(aq)

Overall equation:

Co(OH)2(s)+ 6NH3(aq) ---------->[Co(NH3)6]^2+(aq) + 2OH^-(aq)

The increased solubility of the cobalt salt in the presence of ammonia is as a result of the formation of the hexammine cobalt II complex shown above.

Knet= Ksp×Kf

Ksp of Co(OH)2= 5.92 × 10^-15.

Kf= 7.7 x 10^4

Knet= 5.92 × 10^-15 × 7.7 x 10^4

Knet= 4.56×10^-10

Note Knet is the equilibrium constant of the overall reaction.

Match the following. 1. A mixture that does not have a uniform composition and the individual components remain distinct. polar
Ganezh [65]

Answer:

Explanation:

1. A mixture that does not have a uniform composition and the individual components remain distinct.

HETEROGENEOUS

An heterogeous mixture is a mixture with components in different phases.

2. A mixture that does have a uniform composition throughout and is always in the same state.

HOMOGENOUS

Homogenous mixtures have just one phase that is uniform all through.

3. A substance that will not dissolve in a solvent.

INSOLUBLE

When a solute cannot dissolve in a solvent to form a solution, we say it is insoluble.

4. A homogeneous mixture

SOLUTION

Solutions are made up of homogenous mixtures solute and solvent.

5. A molecule with no internal charge variation due to bonding.

NON-POLAR

Even distribution of charges especially between species whose electronegativity difference is 0 would lead to the formation of a non-polar compound. Here,

6. A molecule with an uneven distribution of charge due to unequal sharing of electrons during bonding

POLAR

Unequal sharing of electrons forms a polar compound. The more electronegative attracts the shared electron to itself and there is separation of charges. This leads to polarity.

7. A solution which has dissolved as much solute as it can at a particular temperature.

SATURATED

A saturated solution cannot dissolve more solute beacuse it contains enough solute as it can dissolve at a temperature.

8. A solution which is still able to dissolve solute.

UNSATURATED

An unsaturated solution is able to dissolve more solute.
