TASK TWO: Dissolving

TASK THREE: Neutralisation

How much sugar will dissolve in a small amount water?

Indicators can be used to find out whether a solution is acid, alkaline or neutral. Universal indicator can be used to find the pH of a solution.

In a beaker with 2 – 3 cm of water add a small spoonful of sugar and stir it until it all dissolves. How many spoonfuls can you add until it will not dissolve anymore? _________________________________________

• • •

Acid - red, pH less than 7 Neutral - green, pH = 7 Alkali - blue/purple, pH greater than 7

Look at the picture below:

When you react acids with alkalis, a neutralisation reaction takes place. The acid is cancelled out by the alkali. In a neutralisation reaction, a salt and water are produced.

Describe what happens during a neutralisation reactions, include a description of what happens to the pH during this type of reaction. ___________________________________________________________________________________ ___________________________________________________________________________________ Which of the ideas do you think would work to dissolve more sugar? Can you think of any ideas of your own? ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________

TASK FOUR: Solids, liquids and gases Everything is made up of particles that are too small to see. The three states of matter are SOLID, LIQUID and GAS. They are have different properties due to the arrangement and movement of their particles.
