If you have 40 grams of potassium nitrate in 100 grams of water at 20 C:

a. How many grams of potassium nitrate will dissolve?

b. How many grams of potassium nitrate will fall to the bottom of the container?

c. At this temperature, 20 C, is this solution saturated, unsaturated or

supersaturated? EXPLAIN.

d. At what temperature will the amount of potassium nitrate that fell to the bottom will also dissolve?

e. If this solution was heated to 90 C, would the solution be saturated, unsaturated or supersaturated? EXPLAIN.

Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
