Question

12. Cyanide ion is an effective masking agent but not for
A) Cd2+, Zn2+
B) Hg2+, Ca2+
C) Cat,
D) Ba2+, Cu2+
Ni2+​

Answer 1

Answer:

The Cyanide ion is an effective masking agent but not for D) Ba2+, Cu2+ and Ni2+​.

Explanation:

• A cyanide is the chemical compound that will contain CN of a functional group it is known as cyano group.
• It contains carbon atom which has a triple- bonded nitrogen atom.
• The formula of cyanide is CN-
• They cyanide consists of one nitrogen atom and carbon atom which is connected to each other having bond which are triple it is called as cyanide anion or cyanide ions.

Uses of cyanide:

1) It is used in gold mining.

2) It is used for stabilizing the ions that are electron during electro plating.

3) It is used in making the jewellery.

4) It is used in plants for germination.

• A Barium also known as Barium cation which has a divalent metal cation and also have a monoatomic dictation.
• A cupric ion is an copper ion that will carry out the double positive charge.
• A Nickel II ion is a cation of the nickel that in which it carries the double charge.

Therefore, the Cyanide ion is an effective masking agent but not for Ba2+, Cu2+ and Ni2+.

Answer 2

Answer:

OPTION (d) $Ba^{2+}$, $Cu^{2+}$, $Ni^{2+}$

Explanation:

• Cyanide is basically a rapidly acting chemical that is also considered deadly and can exist in several forms.

• Cyanide ion consists of a carbon atom with a triple-bonded nitrogen atom.

• Its formula is written as $CN^{-}$.

• It has one nitrogen atom and one carbon atom connected to each other through a triple bond and the whole ion is eventually known as a cyanide anion or cyanide ion.

Below are the uses of cyanide in everyday life:

• It is frequently used in gold mining.
• It is also used for the purpose of stabilizing the ions.
• For making pieces of jewelry, cyanide is used.
• In the process of germination also cyanide is often used.

Final Answer:

Cyanide ion is an effective masking agent but not for $Ba^{2+}$, $Cu^{2+}$, $Ni^{2+}$
