concentration and dilution

Question 1

is water a solvent or solute?

Answer 1

solvent

Question 2

is salt a solvent or a solute?

Answer 2

solute

Question 3

what is concentration of a solution? explain

Answer 3

It is a ratio between the amount of solute and the total quantity of the solution.

A concentrated solution contains a large amount of dissolved solute in relation to the volume of the solution

Question 4

explain a diluted solution

Answer 4

A diluted solution contains a small amount of dissolved solute in relation to the volume of the solution.

Question 5

what is the unit of concentration?

Answer 5

g/l

Question 6

what is the unit of mass of solute

Answer 6

g

Question 7

what is the unit of volume of a solution?

Answer 7

L

Question 8

what equation do you use to determine the concentration of a solution in g/L?

Answer 8

c = m/v

Question 9

what does the percentage show?

Answer 9

It shows the amount of solute per 100 ml of solution.

Question 10

how do you dilute a solution?

Answer 10

add solvent to the original solution to reduce its concentration.

Question 11

what formula must you use for dilution problems?

Answer 11

c1v1 = c2v2
