- Strontium hydroxide is one of the products formed when strontium reacts with water. Why is strontium being described as being oxidised in this reaction?
- At what concentration does sulphuric acid act as an oxidising agent? (or where should iIlook to find this out - I searched through Google!) Does hydrochloric acid act as an oxidising agent at any concentrations?
- Copper is deposited over zinc sheet, when zinc is placed in copper sulphate, since zinc is more electropositive than copper. Instead of getting brown colour of copper on the zinc, a black colour was observed. Please explain this. Similarly, a black colour was obtained on iron during the electrolysis of copper sulphate with iron as negative electrode. Here also we expected brown colour of copper on iron.
