Answer 1

The answers for the following questions is given as follows.

(a). differentiate between a saturated and an unsaturated solution. how will you test whether a given solution is saturated or not  but.

• A solution in which no greater solute can be disintegrated/dissolved at that temperature is known as a saturated solution.
• A solution wherein the greater quantity of solute may be disintegrated/dissolved without raising its temperature is called an unsaturated association.
• A more amount of solute may be added to the solution to test the saturation or unsaturation of a solution. The solution will be called unsaturated, if that solute gets dissolved in the solution.
• Add some more solute to the solution, if this time, the solute does not dissolve in the given solution, then it will be a saturated solution.

(b). how would you prepare a saturated solution of sodium chloride in the water a given 25° celcius? what will happen if this solution is cooled to 10°celcius

• Take a few glasses of water in measuring utensils and warmth it progressively with the help of burner.
• At this point, start adding sodium chloride salt to the boiling water with a spoon and blend it with a glass pole constantly so sodium chloride keeps dissolving in water.
• Take the temperature of the water as much as 25°C and afterwards preserving this temperature consistent, continue along with sodium chloride till no extra sodium chloride breaks down in it and a few undissolved crystals will be left on the base.
• The contents of the beaker are now filtered and the clear solution obtained is the saturated solution of sodium chloride at 25°C.
• If the temperature is decreased from 25°C down to 10°C, at that factor, a portion of the crystals of sodium chloride will isolate from the arrangement as solute crystals.
