burn Mg

AIM: to make a metal oxide and observe the difference in properties of the product compared to the reactants

EQUIPMENT: a piece of magnesium, Bunsen burner, safety glasses, metal scissor tongs

METHOD:

1) light your Bunsen burner

2) hold you piece of magnesium in the scissor tongs. ensure you are holding onto the very tip pf the magnesium.

3) place the other end of the magnesium into the Bunsen flame

4)when the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes. 

RESULTS: i saw a bright light

DISCUSSION:when a metal reacts with oxygen it forms a metal oxide, and in this experiment we made magnesium oxide, it gave off a bright light.

CONCLUSION: this worked because it gave a bright light like it was meant to 

testing pH levels

AIM: to test the pH of a range of household chemicals.

EQUIPMENT: a variety of household chemicals, spotting tile, red litmus paper, blue litmus paper, universal indicator solution, safety glasses.

METHOD: 
1) add a few drops of each chemical to a spot on your spotting tile. if a substance is solid or powered you will need to mix it with a few drops of water before testing it.

2) test the chemicals with both red and blue litmus paper.

3) test each chemical with a few drops of universal indicator.

RESULTS AND DISCUSSION: 
1) dish washing power. I believe that this is a base as in all of the tests i did the colour was a blue and on the pH scale that means it is a weak base

2) vinegar. I believe that this is a mild acid because all of the tests I ran the colour was orange, indicating that it has a ph level of 3-5

3) baking soda. I also believe that this is a strong acid, because with the indicators came back with a strong red colour, with a predicted 1-3 on a Ph scale

CONCLUSION:
this experiment worked because colours were shown when they were meant to, as shown in this photo, curtsy to Mr Heath
