Can you check if this is correct please:

Question

Reactivity order for these metals (top being most reactive):
- Magnesium (I'm not sure if Magnesium or Manganese should be at the top)
- Manganese
- Zinc
- Copper

Reactivity order for these acids (top being most reactive):
- Sulfuric acid
- Hydrochloric acid
- Ethanoic acid
- Citric acid
Thank you :)

Answer 1

The activity series is ok. I don't know how to answer the second; reactivity is based on concns. If we base it on Ka values, then I would rank them HCl, citric, 100% H2SO4, ethanoic, I am a little unconfortable with this because of the placement of H2SO4; however, PURE H2SO4 is not a very strong acid. Add a little water (always add acid to water not water to acid) and the reactivity goes up exponentially. Look in your notes and/or your text to verify this.
