A nitrite solution is added to a saturated solution of iron (II) acidified with dilute acetic acid or with dilute sulphuric acid. If any reactions occurs then write the name and chemical composition of the products formed. Also write the chemical equations involved.

Explanation

`NO_(2)^(-) +CH_(3)CO OH to HNO_(2)+CH_(3)CO O^(-)`
`3 HNO_(2) to H_(2)O +HNO_(3)+ 2 NO uarr`
`NO uarr + Fe^(2+) +SO_(4)^(2-) to [FeNO]SO_(4)` (Nitroso ferrous sulphate)
