The equation below illustrates the process of Pb2+ (aq) + 11- (aq) → Pblu (s)
a) dissolution
b) precipitation
c) decomposition

The correct answer is - b) precipitation.

Explanation:

In the given question the lead ion in an aqueous solution is mixed with the Leutium ion in an aqueous solution and forms an insoluble or solid salt. This type of reaction is referred to as precipitation reactions in chemistry.

Such reactions are helpful in determining if a particular ion is present in the solution or not.

Pb2+ (aq) + lu- (aq) → Pblu (s)

passing a magnet thought the

mixture , because iron gets attracted to magnet .
