What are X and Y, respectively in the following reactions?
`Au + "aqua regia" to Au CI_4^- + H_2 O + X`
`pt + "aqua regia" to Pt CI_6^(2-) + H_2 O + Y`

A

`N_(2)O,NO`

B

`N_(2)O,N_(2)O`

C

NO, NO

D

NO, `NO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`3Au+underset(("aqua-regia"))(4HNO_(3)-3HCl)iff 3AuCl+underset((x))(NO)+H_(2)O`
`3Pt+underset(("aqua-regia"))(4HNO_(3)+12HCl)iff 3" PtCl"_(4)+underset((Y))(4NO)+8H_(2)O`
