Explanation / Answer

1.

A solution will form between two substances if the solute-solvent interactions are of comparable strength to the solute-solute and solvent-solvent interactions.

2.

The solubility of a solid is highly dependent on temperature.

3.

As the pressure increases the solubility of a gas in a liquid increases.

Henry's Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

Answer is:

The solubility of a gas in water increases with increaseing pressure.

4.

P = K * x

where P is partial pressure of NH3 = 0.022 atm

K is Henry's constant

and x is solubility = 1.30 M

K = P/ x

= 0.022 atm / 1.30 M

= 0.01692 atm. L / mol

= 59.0 mol / atm.liter

= 59.0 M / atm
