0.036g O2 dissolves in 4 liter of water at 25°C and at O2 pressure of 600 mmHg, calculate the solubility coefficient.

How many grams of O2 can be dissolved in 500 ml of aqueous solution when the total pressure above the mixture is 760 mmHg? The partial pressure above the O2 in solution is 0.04 atm and the temperature is 25° C.

As the temperature increases the solubility of gases decreases………….

The attractive cohesive forces, which may occur in gases, liquids, or solids, are called………..

Complete miscibility occurs when: The adhesive forces between different molecules (A-B) ………..cohesive forces between like molecules (A-A or B-B).

Partial miscibility results when: Cohesive forces of the constituents of a mixture are low different

The non polar molecules (B) will be squeezed out by the powerful ……forces existing between the molecules of the polar liquid.

If the added material is soluble in only one of the two components, the mutual solubility of the liquid pair is …………

If the added material is soluble in both of the liquids, the mutual solubility of the liquid pair is ………

Decrease in mutual solubility of two partially miscible solvents by another agent is ordinarily referred to as blending.

Systems of ………… include the most important type of pharmaceutical solutions.

If Temperature increase the solubility of solid in ideal solution increase

Many important drugs belong to the class of stronge acids and bases.

When the concentrations of salt and acid are equal………….

Weak electrolytes can behave like strong electrolytes or like nonelectrolytes in solution

Solubility increases with …………particle size

symmetric particle can be less soluble than an unsymmetric one.

In the oil phase, the concentration of monomer or dimer depends on the type of oil

In the aqueous phase, the concentration of unionized or ionized depends on…………………
