Water C 1 Flashcards pp. 45-53
2
Use the graph on pg. 46 to answer some of these questions.
3
Give an example of a solute and a solvent.
4
Solvent: water Solute: kool-aid (or sugar) OR Solvent: laundry detergent Solute: grease stain
5
If you have 60g KNO 3 at 40 o C in 100g of water, is the solution… saturated, unsaturated or supersaturated?
6
Saturated
7
If you have 80g of KNO 3 at 10 o C, 100g of water, is the solution… saturated, unsaturated or supersaturated?
8
Supersaturated
9
If you have 70g of KNO 3 at 80 o C, in 100g of water, is the solution… saturated, unsaturated or supersaturated?
10
Unsaturated
11
What is the minimum amount of water needed to dissolve 70g KNO 3 at 80 o C?
12
At 80 o C 160g KNO 3 = 70g KNO 3 100g H 2 O Xg x = 43.8g
13
What mass of KNO 3 will dissolve in 100g of water at 10 o C?
14
About 20 g KNO 3
15
How much KNO 3 will dissolve in 250g of H 2 O at 50 o C?
16
At 50 o C 80g = X 100g 250g x = 200g KNO 3
17
If you have 50g KNO 3 at 50 o C, in 100g H 2 O how much more KNO 3 must be added to saturate the solution?
18
80g is saturated so subtract 50g and 30g more of KNO 3 must be added.
19
An alka-seltzer tablet is placed in water and then the medicine is consumed. Identify the 3 underlined substances as solute, solution and solvent.
20
Solute - Alka-seltzer tablet Solvent - water Solution - medicine
21
What is the percent concentration of a solution that contains 45g of weed killer in 1500g of water?
22
45 x 100 (45g + 1500g) =2.9%
