Salty water

Question 6

What is solubility?

Answer 6

A mass of solid that will saturate 100g of water at a particular temperature.
Units = g/100g water

Question 7

Answer 7

Temperature
Stirring
Volume of solvent
Mass of solute

Question 8

What is the formula for working out solubility?

Answer 8

Solubility (g/100g of water) = mass of solute/mass of solvent x 100
