What is solubility?

• The number of ml of solvent in which 1 gram of solute will dissolve

• The concentration of solute in a saturated solution at a certain temperature and spontaneous interaction of two or more substances to form a homogeneous molecular dispersion

• The ability of a solute to exist in two different states at a definite temperature

• The process by which solvent molecules surround solute molecules

What does USP/NF define?

• The process of forming a homogeneous mixture

• The number of ml of solvent in which 1 gram of solute will dissolve

• The interaction between solute and solvent molecules

• The increase in solubility due to temperature

What type of solution contains the dissolved solute concentration below that is necessary for complete saturation at a definite temperature?

• Saturated solution

• Supersaturated solution

• Unsaturated solution

• Homogeneous solution

Which solution contains more dissolved solute than it would normally contain at a definite temperature?

• Supersaturated solution

• Saturated solution

• Unsaturated solution

• Dilute solution

What is a saturated solution?

• It contains more solute than normal at a given temperature.

• It contains the maximum amount of solute that it can dissolve.

• It contains less solute than the saturation point.

• It contains a mixture of polar and nonpolar solutes.

What are polar solvents?

• Solvents that dissolve ionic solutes and other polar substances.

• Solvents that dissolve nonpolar substances only.

• Solvents unable to ionize weak electrolytes.

• Solvents that act as intermediates between polar and nonpolar substances.

Which statement describes nonpolar solvents?

• Solvents that dissolve ionic solutes.

• Solvents with low dielectric constants, unable to ionize weak electrolytes, often hydrocarbons.

• Solvents that mix polar and nonpolar liquids.

• Solvents that dissolve hydrophilic substances.

What are semipolar solvents?

• Solvents that dissolve nonpolar substances.

• Solvents that act as intermediates to bring about the miscibility of polar and nonpolar liquids.

• Solvents with low dielectric constants.

• Solvents that ionize strong electrolytes.

Which factor in solubility of gases in liquids states that the amount of a gas dissolved is directly proportional to the partial pressure of the gas?

• Effect of temperature

• Salting out

• Effect of pressure

• Miscibility
