Question

Determine one cation and one anion in the given unknown salt m ;

Answer 1

Cation is Positively charged while anion is negatively charged so in the unknown salt M.

The salt M is Sodium Chloride (Nacl).
Sodium ions are metallic ions so they are Cation while Chlorine ions are non-metallic ions so they are anion.

Na+ --- Cation
Cl- --- Anion

Answer 2

One cation and one anion in the given unknown salt M can be detected with the help of dry and wet test of ions

Explanation:

Identification of anionic radical by DRY Test:-

• In this small amount of salt is used and is observed for colour, small moisture

• The temperature should be room temperature at which the study is done.

• Carbonate, sulphide, sulphite, nitrite and acetate reacts with sulphuric acid to evolve various gases.

• The evolved gases is studied to collect the information of anionic radicals

Identification of anionic radical by WET Test

• A Confirmatory test of anions is carried out by dissolving in water. It is soluble in water and then using sodium carbonate extract.

• Using sodium extract the confirmatory test of anions is done

Qualitative analysis can be used to determine the cation and anion in the salt.
