Solution And Solubility

Question 1

What’s a solution

Answer 1

A homogenous mixture of two or more substance at a particular temperature and pressure

Question 2

What is the solute?

Answer 2

The substance dissolved in a solvent to form a solution

Question 3

What is a solvent?

Answer 3

The dissolving medium of a solution

Question 4

What is solubility?

Answer 4

Amount of solute that the solvent can dissolve

Question 5

What’s an unsaturated solution?

Answer 5

Is a solution that has not reached the limit of solute that will dissolve in a solvent at a particular temperature and pressure

Question 6

What is a saturated solution?

Answer 6

A solution that contains as much solute as will dissolve at that temperature and pressure

Question 7

What is Henry’s law?

Answer 7

It states that the pressure of the gas over a solution is directly proportionate to the solubility

Question 8

True or false

Solubility of solid increase with temperature

Answer 8

True

Question 9

True or false

Solubility of gases decrease with increase in temp

Answer 9

True

Question 10

What is a supersaturated solution?

Answer 10

When a solution is saturated at an elevated temperature and then allowed to cool but all the solute it remains dissolved

Question 11

Increase in pressure decreases the solubility of gases true or false

Answer 11

False increases

Question 12

Does pressure have an effect on solid solute solubility?

Answer 12

No

Question 13

What is the formula that Henry’s law gives?

Answer 13

Sg=k.Pg

Question 14

What is hydrostatic pressure?

Answer 14

Pressure present wishing fluid at rest, increases with deeper oceans

Question 15

Describe decompression sickness

Answer 15

Occurs when nitrogen that is dissolved in bloodstream exits the vessel inadequately as the diver ascends quickly to the top of the sea

Question 16

Physiological effect of the bends on the body

Answer 16

Nitrogen cause bubbles in the bloodstream which block blood vessels
