Interpretation Introduction

Interpretation:

The uses of the given compounds have to be described.

Concept introduction:

Sodium salts

• The element sodium is denoted by the formula is $\text{Na}$.
• The atomic number of sodium is 11.
• Sodium metal was first identified and isolated by electrolysis process by Humphry Davy in 1807.
• Sodium gets 6^th place in the list of most abundant element in earth’s crust.
• Sodium is more reactive and it does not available in free form.  It can available in many forms of compound like ${\text{NaCl, Na}}_{\text{2}}{\text{CO}}_{\text{3}}\text{, NaOH}$.

Potassium salts

• The element sodium is denoted by the formula is $\text{K}$.
• The atomic number of sodium is 9.
• Potassium gets 17^th place in the list of most abundant element in earth’s crust.
• Potassium occurs only in ionic salt forms in nature.
• Potassium ions plays necessary role in living cells.
• Sodium is more reactive and it does not available in free form.  It can available in many forms of compound like ${\text{KOH, KO}}_{\text{2}}$.
