Question

action of conc.hcl on ferrous sulphate solution

Answer 1

- A measurement of pH shows that the latter increased: the solution is less acidic, hydrogen ions therefore have been consumed.
- The addition of silver nitrate leads to the formation of a white precipitate which indicates that the chloride ions are still in solution.
- The test for iron (II) ions is positive: Iron (II) ions (Fe 2+) have formed.

- The reactants are substances initially gathered: iron and hydrochloric acid.
- Products are substances that have formed: dihydrogen and iron (II) ions that form with chloride ions a solution of Iron(II) chloride
