1. List the solutions in order from most acidic to least acidic (most basic).
The most acidic is b i think because it’s more colourless or yellow’s.
2. Which solution do you think was neutral? Explain how you know.
I think magnesium Ribbon was the most neutral because it didn’t change colour as much as the other solutions.
3. You used two bases. Explain how you would know which solution was more alkaline (more basic)?
I think solution B and A is more acidic because and D and C are more basics because B and A have more Reds and yellows.
4. How can magnesium metal be used to distinguish between an acid and a base?
One bubbles and one doesn’t.
5. What colour would each of the five indicators be in a solution that is pH 3?
Magnesium ribbon - Colourless Blue/Red litmus - red
Bromothymal - yellow
Phenolphthalein - Colourless
Methyl orange - red
Blue/Red litmus - red
Bromothymal - yellow
Phenolphthalein - Colourless
Methyl orange - red
