Sodium Hydroxide belongs to the category of inorganic compounds and is usually found in the form of a white solid at room temperature.

Explanation:

Summary :-

• IUPAC Name - Sodium Hydroxide / Sodium oxidanide
• Chemical Formula - NaOH
• Molar Mass - 39.997 g/mol
• Density  - 2.13 g/cm³
• Melting Point - 318.4 °C
• Boiling Point -  1.388 °C

Physical Properties:-

• Sodium Hydroxide in its pure form is a white crystalline solid.
• It is odourless.
• It is soluble in water, glycerol and ethanol. When solid sodium hydroxide is mixed with water it results in a highly exothermic reaction.
• Has a higher viscosity than water about 78 mPas.
• It can form several hydrates.
• It can rapidly absorb carbon dioxide and water from the air. It can also exist in the form of a liquid.

Chemical Properties:-

• It has an ionic bond.
• It can react with protic acids to form water and salts.
• It has high acidity of 13.

Answer 2

Answer:

It is also known as sodiumbycarbonate (NaOH). It is a salt.It is made by when sodium is mixed with water. When sodium hydroxide is mixed with 10 H2O it becomes washing soda
