Water

100 grams of solution + 100 grams of solute = 200 grams of solution

The particles don't disappear they stay in the solution so  they count to the overall weight

1. The particles in a solid are held together tightly.

2. When the solid dissolves the particles separate.

3. If you filter a dissolved solid it will pass through because the particles are not connected

Water is the most common solvent. It is  cheap and dissolves lots different solutes.

Other liquids can also be used as solvents. Solutes that are insoluble in water may dissolve in other solvents.

If you keep adding solutes to a solvent, you will get to a point where no more will dissolve this is called a saturated solution  

Solutions and mixtures can be separated using different methods (shown over the next few cards)

Used To Separate: 

solid particles which don't dissolve from the liquid they are in.

Examples:

• Tea leaves from a cup of tea
• Sand from a mixture of sand and water

Used To Separate: 

dissolved substances from a solution

Examples:

• Salt from salt solution

Used To Separate: 

the liquid from the dissolved solid in a solution or one liquid from a mixture of liquids

Examples:

• water from salt solution
• alcohol from a mixture of alcohol and water

Used To Separate: 

individual colours from a mixture of colours

Examples:

• the colours found in ink 
• the food colourings found in fruit juice
