For testing halogens in an organic compound with `AgNO_(3)` solution, sodium extract (Lassaigne's test) is acidified with dilute `HNO_(3)`. What will happen if a student acidifies the extract with dilute `H_(2)SO_(4)` in place of dilute `HNO_(3)` ?

Text Solution

Verified by Experts

White ppt of `Ag_2 SO_4` will be formed and the student may be mistaken for white ppt. of AgCl due to the presence of Cl.
