Study Notes
Preparation of Metallic Sodium
- Metallic sodium is produced through electrolysis of a molten mixture containing 40% sodium chloride (NaCl) and 60% calcium chloride (CaCl2) using a Down’s cell.
Sodium Chloride (NaCl) Uses
- Commonly known as table salt, NaCl serves as a preservative in pickles, meat, and fish.
- NaCl is essential in the manufacturing of sodium hydroxide (NaOH), chlorine gas (Cl2), and soap.
- In Nelson and Castner-Kellner cells, NaCl acts as the primary raw material for producing caustic soda (NaOH).
Sodium Hydroxide (NaOH) Applications
- NaOH, also known as caustic soda, is utilized in the production of soap, dyes, and artificial silk.
- It plays a role in refining bauxite mineral.
Sodium Bicarbonate (NaHCO3) Characteristics
- Commonly referred to as baking soda, NaHCO3 is used in effervescent beverages and fruit salts.
- It serves a function in fire extinguishers and wool washing in the form of sesquicarbonate.
Sodium Carbonate (Na2CO3·10H2O) Insights
- Known as washing soda, Na2CO3·10H2O is crucial in glass manufacturing, soap, washing powder, and softening hard water.
- A mixture of sodium carbonate and potassium carbonate is referred to as a fusion mixture.
Sodium Sulfate (Na2SO4·10H2O) Attributes
- Known as Glauber’s salt, Na2SO4·10H2O is primarily used as a purgative.
Sodium Thiosulfate (Na2S2O3·5H2O) Functions
- Commonly called hypo, Na2S2O3·5H2O is an important chemical in photography, functioning as a fixing agent.
