What would you do to change a saturated solid/liquid solution to an unsaturated solution
Semenov [28]

Explanation:

Saturated solid/liquid solution is changed to an unsaturated solution by the dilution process.

When the saturated solution is diluted by addition large quantity of solvent it changed to an unsaturated solution.

Saturated solid/liquid solution can also be changed to an unsaturated solution by increasing the temperature or heating the solution.

A saturated solution is a solution where further solute will not dissolve in the solvent.

Which way of expressing concentration includes (a) volume of solution;
Sergio [31]

Molarity and normality are the ways of expressing concentration which includes the volume of the solution.

As we know,

Molarity is defined as the number of moles of solute dissolved in 1L of the solution. Thus,

M = no. of moles of solution/ Volume of solution on litres.

while, Normality is the number of gram equivalents of the solute dissolved per litre of the solution.

N = Gram equivalent of the solute/ volume of solution in litres.

while, the other concentration expressing terms such as mole fraction, molality includes the mass of the solution and solvent respectively.
