What are the essential characteristics of a true solution ?
A true solution (simply a solution) shows the following characteristics. It is clear and transparent, the solute particles in a true solution do not settle down, a true solution does not scatter light and etc.
How is the concentration of a solution measured ?
In chemistry, most reactions are carried out in solutions. In order to perform calculation, it is necessary to know concentrations of the solutions. The quantity of solute dissolved in a given mass or volume of the solution or the solvent is called concentration of the solution.
What do you mean by the unsaturated and saturated solution ?
A solution in which more solute can be dissolved at any fixed temperature is called an unsaturated solution. A solution in which no more solute can be dissolved at any fixed temperature is called a saturated solution.
How to prepare saturated solution of a substance ?
Take about 100 ml of water in a beaker. Keep this water at the desired temperature by using a water bath. Add a small quantity of the given substance into the water and dissolve it by stirring. Add a little more substance and again stir to dissolve it.
How does a true solution differ from a colloid and a suspension ?
A true solution (or simply a solution) differs from a colloid and a suspension as follows. A true solution is a homogeneous mixture of two or more than two substances whereas a colloid is a homogeneous-looking, but heterogeneous-mixture and a suspension is a heterogeneous mixture of a solid dispersed in a liquid, or gas.
What is meant by the term solution in chemistry?
A homogeneous mixture of two or more substances is called a solution. Homogeneous means physically and chemically uniform throughout. For example..
