Question

part e
what is the solubility of licl at 40c?
a it does not exist
b 100 g
c 65 g
d 90 g
part f
if you make a solution of rbcl with 50g at 10c, how would you classify
the solution?
a unaturated
b none of the above
c saturated
d supersaturated
part g

Explanation:

Part E

Step1: Locate 40°C on the x - axis

Move vertically from 40°C on the x - axis.

Step2: Find the LiCl curve

Locate the LiCl curve and check the y - axis value at the intersection.
The LiCl curve at 40°C intersects the y - axis at approximately 90g.

Step1: Locate 10°C on the x - axis

Move vertically from 10°C on the x - axis.

Step2: Determine the solubility of RbCl

Assume RbCl has a solubility curve (similar to common salts). If the amount of solute (50g) is less than the solubility at 10°C (if solubility is higher than 50g), the solution is unsaturated.

Answer:

D. 90 g
