Answer 1

Answer:

NaOH - sodium hydroxide or caustic soda

Answer 2

Answer:

NaOH

• Caustic soda is an alkali salt which is also called Lye. It is the common name of sodium hydroxide (NaOH)

Sodium hydroxide can be prepared by various methods like:

• Castner-Kellner process
• Loewig’s process

Properties of Caustic Soda

• It is a white solid which has a melting point of 591K
• It is a stable compound.
• NaOH is bitter and has a soapy feel to it.
• It is highly soluble in water and moderately soluble in alcohol.
• Sodium hydroxide is strongly alkaline in nature.

Caustic Soda Uses

• It is used as a cleansing agent and in the manufacturing of washing soda.
• Some times, sodium hydroxide is also used as a reagent in the laboratories.
• It is used in the preparation of soda lime.
• It is used in the extraction of aluminium by purifying bauxite.

NaHCO

• Baking Soda is also defined as Sodium Bicarbonate.Solvay process is used for the production of sodium bicarbonate and sodium carbonate industrially.

 

Properties of Sodium Bicarbonate

• It is non-flammable.
• Powder dust is not as explosive.
• It has a melting point of 500
• NaHCO3 is a white crystalline solid which is odourless.
• It is basic in nature.

Uses of Baking Soda

• Reduces the acidity in the stomach.
• Acts as an antacid which is used to treat stomach upset and indigestion
• Used in the process of washing as a water softener
• Due to the formation of soapy foam, it is used in fire extinguishers
• Removes the dirt off materials without damaging the properties of the material
• Acts as a pesticide
• Used in baking industries as carbon dioxide is generated (due to the decomposition of NaHCO3) which helps in the raising of the dough
• It is used in ear drops, cosmetics and personal care products
• It is used as a neutralizer to neutralize the effect of acid
