INTRODUCTION:

Acids
Acids are any chemical compound that, when dissolved in h2o (water) gives a solution with the pH below 7.0.

Acids are sour, they also destroy chemical properties of bases. Acids conduct an electrical current through them.

Common Acids
Acetic acid is found in vinegar. Vinegar is used for cooking things, treating jellyfish stings and pickling.
Another common acid is sulphuric (Sulfuric) acid, which is a strong acid. Sulphuric (Sulfuric) acid is soluble in water at all concentrations. It is used for car batteries, ore processing, oil refining and fertiliser manufacturing. Sulphuric (Sulfuric) acid is also a constituent on acid rain.

Bases
Bases are the chemical opposite of acids. A reaction between a base and an acid is called neutralisation. Bases and acids mixed together produce water and salts.

Taste and Texture: Bases taste bitter and have a slimy or soapy feel when touched.
Reactivity: Caustic on organic matter
Electric conductivity: Aqueous solutions or molten bases dissociate in ions and conduct electricity

Common Bases
Ammonia base is a weak base and can be found in window and floor cleaners.

Brief Explanation of Experiment
We have tested household substances to determine their pH level and description of pH(strong/weak, acid/base or neutral)

Indicator
An indicator is a substance that determines whether a substance is an acid/base/neutral.

It changes the colour of the substance depending on how much water the substance contains. The pH measures the acidity in a solution.

Prediction:
Water: 7.0, Green, neutral.
Orange Juice: 3.0, red, strong acid.
Lido Lemonade: 5.0, red-orange, weak acid.
Coca Cola: 3.0, red, strong acid.
Skim milk: 5.0, red-orange, weak acid
