A solution can only be a mixture of two or more substances in different physical phases.
False
In a binary solution, the solute is the component present in large quantity.
False
A supersaturated solution contains less solute than necessary to saturate it at a given temperature.
False
Hydrated salts are an example of a solid-liquid solution.
True
Alloys are an example of a liquid-solid solution.
False
An unsaturated solution can dissolve more solute without raising the temperature.
True
The maximum amount of a solute that can be dissolved in a given amount of solvent at a given temperature is termed as its solubility at that temperature.
True
Henry’s law states that the partial pressure of the gas in vapor phase is inversely proportional to the mole fraction of the gas in the solution.
False
Greater the value of KH, higher the solubility of the gas according to Henry’s law.
True
The value of KH increases with an increase in temperature according to Henry’s law.
