Making another salt

Making another salt

Aim:
To make copper sulfate crystals (salt) by neutralizing copper oxide (base) with a sulfuric acid (HSO)

Method:
Follow the method on Page 39 of your Scipad book.

Observations: (write an observation for each key stage of the process - full sentences please)

1.when we added the copper oxide to the acid , the liquid turned blue and the copper oxide dissolves

2.the liquid was clear blue after we filled it
3.when the water evaporated (4 days later) there were 

Results:
Add 3 photos for the final stages of the experiment to illustrate the process.

Conclusion(write a single sentence as conclusion - remember to look at your aim and write your conclusion as a response to your aim)

Word equation for the reaction:


Balanced chemical equation for the reaction:

Our first Year 10 Chemical Reactions

Our first Year 10 Chemical Reactions

1. Magnesium reacting with oxygen:

Method: We held a strip of magnesium metal in the hottest part of a bunsen burner flame till it caught fire. We didn't look directly at the reaction because (safety reason)
Observations:
1. The magnesium metal was a (description - colour, lustre, malleability)
2. The magnesium burned with a (describe what you saw)
3. After it burned (describe what the product looked like)

Include a photo/video of each observation and label them.

2. Iron filings reacting with sulphur:

Method: We mixed equal amounts of iron filings and sulphur then used a magnet wrapped in paper to separate them. We mixed them again and added the mixture to a test tube and heated strongly.
Observations:
1. The iron filings were (describe the colour etc)
2. The sulphur was (describe the colour etc)
3, When we heated the tube (describe what happened)
4. After the reaction (describe the product)

Include a photo/video of each observation and label them.
