4. Enumerate the chemical reaction involved inthe separation/identification of Group iii-a cations

5. Write the chemical reaction involved in the separation/identification of Group iii-b cations​

Answer 1

Answer:

2. Aqua regia, a highly corrosive mixture of concentrated nitric acid and hydrochloric acid, is used to dissolve various metals such as gold and platinum that are not soluble in other types of acids.

Answer 2

Answe

2. Aqua regia, mixture of concentrated nitric and hydrochloric acids, usually one part of the former to three parts of the latter by volume. This mixture was given its name (literally, “royal water”) by the alchemists because of its ability to dissolve gold and other so-called noble metals.
