First Exercise (7 polnts) Diluted and concentrated solutions
A student prepared two solutions in two beakers. To the first beaker, he added two spoons of table salt
with
1 liter of water. To the second beaker, he added three spoons of table salt in the same volume of water.
Each spoon contains 15 g of table salt.
Spoons each containing
15 g of table salt.
1L
water
water
Solution 1
Solution 2
1-Indicate the solute and the solvent in the solutions prepared by the student.
2- Specify if these solutions an aqueous or a non-aqueous solution,
3- Knowing that the solubility of sodium chloride, table salt, is at room temperature is 36 g/1.
Deduce the nature (dilute or concentrated) of each solution.
4- Propose a method so that the two solutions can have the same concentration.
5- List two factors that increase the rate of dissolving the solute in the solvent.​
