A base is the opposite chemical to an acid.  

A base contain hydroxide. ( OH )                

An acid and a base neutralise each other and makes water

                                                   

What is an Acid

Names of acid:                                Formulae of Acids:

Hydrochloric acid                            HCL

Sulfuric acid                                    H2SO4

Nitric acid                                       HNO3

Phosphoric acid                              H3PO4

Acetic acid                          i          CH3COOH     

Citric acid                                      From lemons and oranges   

Formic acid                                   Poison in bee-stings

Tartaric acid                                   

Where do you find acids:                                 What is Acid:

Plaque Acid on your teeth.                                  An acid contains Hydrogen atoms that 

Stomach Acid is Hydrochloric Acid.                  break of to react with a substance. 

Battery Acid is Sulfuric Acid.                                   

Lemons and Oranges have Citric Acid.                     

Vinegar contains Acetic Acid.                                 

Bee-Stings have Formic Acid.                               

Coca-Cola has Carbonic Acid                             

Litmus Color:

Blue litmus paper changes to red in acid.

If you put red litmus paper into acid it stays the same color.

Red Cabbage Indicator

 Aim:

I want to find out how to tell if something is an acid.

Method:

Equipment

• Beaker
• Red Cabbage
• Hot water
• Test tubes ( Test rube rack )
• Acid + hydroxide
• Dropper

Instructions

1. Get your equipment
2. Rip the red cabbage into little bits 
3. Place your ripped red cabbage bits in the beaker
4. Pour 100 ml hot water into the beaker
5. Slowly pour the acid into the one out of the bigger test tubes
6. In the other big test tube, pour hydroxide into it
7. Add the red cabbage water into the two big test tubes ( Use a dropper )
8. Mix ( with the dropper ) both the acid and hydroxide into little test tubes and try to make different colors.

Results

I made red, green, blue and purple by mixing the acid and hydroxide.

I also made a tube have orange, blue, green and purple.

Making Sherbet

 Aim: 

I want to find out how to make sherbet

Research:

Method:

Equipment:

• Cup - Some type of container
• Baking Powder
• Citric acid
• Sugar ( But we used raro )
• Stirring rod ( Popiscle stick )
• Teaspoon

Instuctions

1.  Get your equipment
2. Add a teaspoon of Raro into the cup
3. Add half a teaspoon of baking powder into the cup
4. Add half teaspoon of Citric acid
5. Mix the powder with the stirring rod
6. Taste the sherbet and adjust the flavor as necessary

Results:

The sherbet was sweet before it foamed up. After it's foamed it a little sour.

Disuccion:

Citric acid + Sodium Bicarbonate = Carbon dioxide

C₆H₈O₇ + NaHCO₃ = CO2
