Question

name the reagent from the following which can be used to distinguish zinc nitrate from lead nitrate : a) NH4OH b) NaOH c) BaCl2 d) H2SO4 LE​

Answer 1

Answer:

Ammonium hydroxide - NH4OH

Explanation:

• Addition of an excess of Ammonium hydroxide.
• Lead nitrate results in insoluble white precipitate while zinc nitrate initially forms a white precipitate that soluble in excess of ammonium hydroxide solution

Answer 2

Answer:

The correct option is NH4OH : Ammonium Hydroxide.

Explanation:

Concept : Separation of two compounds : Two compounds can be separated with each other by adding a suitable reagent in which one of the compound forms precipitate and other is soluble. In case the reagent forms precipitate with both the compounds , then only one of the two compounds should be soluble in excess reagent and other should be insoluble.

In case of Zinc nitrate and Lead nitrate, formation of a white precipitate takes place when ammonium hydroxide is added . When excess of ammonium hydroxide is added, white precipitate due to lead is not soluble while that due to zinc is soluble.
