What is a diluted solution?

When a solution has less solute than another and both have the same amount of solvent. And the other way around.

What is a concentrated solution?

When a solution has more solute than another and both have the same amount of solvent. and the other way around.

What is solubility?

How much the solute dissolved is the solvent.

What are ways to make a solution less dilute?

Adding solute or taking away solvent.

What are the ways to make a solution more diluted?

By adding solvent or taking away solute.

How could you separate mixtures?

Filtration, sifting and evaporating the solvent.

What’s a saturated solution?

A solution where the maximum amount of solute is dissolved in the solvent, and no more solute can be dissolved

What does insoluble mean?

That the solute doesn’t dissolve in the solvent,.

What do you call something that DOES dissolve?

Soluble

What is the solute?

The substance being dissolved in the mixture. (E.g sugar)

What is the solvent?

What’s’ the name of the substance that combines the two insoluble substances in an emulsion? Give the example for mayonnaise.

The emulsifier. E.g Egg yolk.

Suspension. E.g juice with pulp

Colloid. E.g milk

What’s the name of the mixture that’s diference can’t be seen?
