Question

What is the difference between caustic soda and baking soda?

Answer 1

Sodium Hydroxide is a crystalline substance that is white and transparent. Due to its corrosive impact on various things, it is usually referred to as caustic soda. It decomposes proteins at room temperatures and can cause chemical burns in humans.

Complete answer:

Caustic soda	Baking soda
Caustic soda has the chemical formula $NaOH$ and the chemical name Sodium. Caustic soda, often known as Lye, is an alkali salt. The corrosive nature of this salt on animal and plant tissues has earned it this name. It can be used in a variety of ways.	Baking soda has the chemical formula $NaHC{O_3}$ and the chemical name Sodium Bicarbonate.
Properties -1) It's a white solid with a melting point of ${591^ \circ }C$ .2) Sodium hydroxide is an alkaline substance.3) It is a long-lasting substance.4) It has a high-water solubility and a moderate alcohol solubility.5) $NaOH$ is bitter and soapy to the touch.6) It has a high-water solubility and a moderate alcohol solubility.	Properties -1) It is non-combustible. 2) Powder dust isn't as explosive as other types of dust.3) It has a melting point of $500^\circ C$ and is an odourless white crystalline solid.4) It is basic in nature.
Uses: It's a cleaning agent, and it's also used to make washing soda. In some laboratories, sodium hydroxide is also used as a reagent. It is a key ingredient in the production of soda lime. It is used to cleanse bauxite in order to obtain aluminium.	Uses: Reduces stomach acidity and acts as an antacid to relieve stomach discomfort and indigestion. As a water softener, it is used in the washing process. It is used in fire extinguishers because it produces soapy foam. Acts as a pesticide by removing dirt from materials without affecting their properties.

Note:
Caustic soda is used to clean process equipment and storage tanks because it dissolves grease, protein-based deposits, fats, and oil when mixed with water and heated. The Castner-Kellner method involves electrolysis of brine solution to produce sodium hydroxide.
