Question

(ii) What is the chemical name of washing soda? Name the three main raw materials
required for making it? Write the reaction involved in the preparation of washing soda.​

Answer 1

Answer:

→The chemical name(IUPAC) of washing soda is Sodium carbonate (Na2Co3)

→ The three main raw materials fire making it are :-

• Sodium chloride (NaCl)
• Ammonia(NH3)
• Limestone (CaCo3)

→Firstly, baking soda or sodium hydrogen carbonate(NaHCO3) is heated. On heating, it produces washing soda along with water and carbon dioxide during the process known as recrystallization. The formula is:-

$\small\bf{2NaHCO_{3}--Na_{2}CO3 + CO_{2} + H_{2}O}$

**its molecular mass is 105. 9888 g/mol

**its density is 2. 54 g/cm²

**melting point is 851°C

**boiling point is 1600°C

Answer 2

Answer:

❣Answer❣

➡The chemical name of washing soda is Sodium Carbonate ( NA2CO3).

➡ The three main raw materials required for making it are :-

⛧Sodium chloride(NaCi)

⛧Ammonia(NH3)

⛧Limestone (CaCo3)

➡ Firstly process, baking soda or sodium hydrogen carbonate ( NaHCo3) is heated. On heating, it produces washing soda along with water and carbon dioxide during the process know as recrystallization. The formula is :-

2NaCHo3 - Na2Co3 + CO2+ H2O
