solubility curves

Question 1

definition of solute

Answer 1

substance that dissolves in a liquid to make a solution

Question 2

definition of solvent

Answer 2

liquid that the solute dissolves in

Question 3

definition of solubility

Answer 3

ability of a solute to dissolve in a solvent

Question 4

saturated solution meaning

Answer 4

when no more of the solute cab dissolve in the solvent

Question 5

how is solubility usually measured and example

Answer 5

grams of solute per 100 grams of solvent
e.g if 23g of a substance can dissolve in 100g of water before solution = saturated, that substance has a solubility of 23g per 100g of water

Question 6

how can you use solubility curves to find the solubility of a substance at a specific temperature and example

Answer 6

1) draw a line from temp up to the curve (x-axis)
2) read across from it to y-axis
e.g 25 degrees is 32g per 100g of solvent

Question 7

formula for calculating solubility

Answer 7

mass of solute dissolved / mass of water x 100
