experiment graphs and questions

[Ice_Phoenix87]

hi,

1. i was wondering if anyone has any ideas about what kinds of graphs i could do with these experiments.

It is in relation to corrosion and shipwrecks and salvage.

the experiment is certain metals and there relation to substances.

metals are:

Cu

Al

Zn

Fe

Pb

Mg

 

the substances are:

NaOH (of unknown concentration)

HCl

H2SO4

distilled water

NH4

(if anyone else can think of any other substances that would be good, please go ahead and tell me)

The metals are put in tests tubes with each individual substance the results are tabled.

What kind of things could graphs be used for?

 

2.Does anyone here know how to write the perfect aim?

 

3. what variables that will affect the investigation?

 

4. controls needed to make the results valid.

 

Any ideas of other type of experiments that could be used to show corrosion, etc in relation to ship wrecks, rusting, etc.

 

thank you very much

When is your homework due?

Which results are you tabulating? Compositional changes in the solutions; of the metals? Changes in mass of the metal?

You should certainly consider using sea water as one of your liquids.

 

"3. what variables that will affect the investigation?"

Are you sealing the tubes? Oxygen content will be critical.

 

"2.Does anyone here know how to write the perfect aim?"

I see the words.....what is the meaning?
