Complete the statement by filling in the blanks with the correct words.
If potassium nitrate is added to water in a beaker to give a homogeneous mixture, then potassium nitrate is referred to as the __________, water as the __________, and the homogeneous mixture as the _______.
(solution/ solute/solvent/saturated solution)
Name the following
The liquid or medium of dissolution which allows the solute to dissolve in it.
If ‘X’ g. of potassium nitrate is added to 100 g. of water at 60°C and the salt dissolves completely then :
(a) is ‘X’ g. the solubility of potassium nitrate at 60°C.
(b) is the solution formed – saturated or unsaturated
(c) if on addition ‘X’ + ‘Y’ g. of potassium nitrate to the same amount of water at the same temperature and the solute now just remains behind after stirring then –
(d) is the solution now – saturated or unsaturated
(e) is ‘X’ + ‘Y’ g. the solubility of potassium nitrate.
State whether the following statement is true or false. If false write the correct statement.
Solubility of most solids – decreases with increase in temperature
Polar compounds are soluble in _____ solvents
Solutions which contain three components are called a binary solution.
In a solution, the component which is present in a lesser amount is called the solvent.
