Question

58.
Study the given graph and answer the following questions
1
whare the solubility of sodium chloride, poistum chloride and
0.
possumchlorate at 50°C.

what happens when a saturated solution of sodium chloride at 50 degree Celsius is cooled to 20 degree Celsius ​

Answer 1

weight of salt = 90 gram,

solubility = 50

sing formula

solubility of solute =

weightofsolventinsaturatedsolution

weightofsoluteinsaturatedsolution

×100

or 50=

weightofsolventinsaturatedsolutio

90gm

×100

so weight of solvent in saturated solution =

50

90gm

×100=180gm

Hence 180 gm of water is required to prepare a saturated solution.
