Question

Na-NaOH- Na2CO3-NaHCO3-Na2CO3

Answer 1

2Na+2H2O=2NaOH+H2
2NaOH+CO2=Na2CO3+H2O
Na2CO3+H2CO3=2NaHCO3
NaHCO3+NaOH=Na2CO3+H2O

Answer 2

2Na + 2H2O = 2NaOH + H2

2NaOH + H2CO3 = Na2CO3 + 2H2O

Na2CO3 + CO2 + H2O = 2NaHCO3

2NaHCO3 = (t) Na2CO3 + H2O + CO2

Answer 3

Na-NaOH: Sodium hydroxide (NaOH) is a strong base commonly known as caustic soda. When sodium (Na) reacts with sodium hydroxide, it forms sodium oxide (Na2O) and hydrogen gas (H2).

2Na + 2NaOH → 2Na2O + H2

Na2CO3: Sodium carbonate (Na2CO3) is an inorganic compound commonly known as soda ash or washing soda. It is a white, crystalline solid that is often used in industry and household products. When sodium reacts with carbon dioxide (CO2), sodium carbonate is formed.

2Na + CO2 + H2O → Na2CO3 + H2

NaHCO3: Sodium bicarbonate (NaHCO3), also known as baking soda, is a white crystalline compound that is used in cooking and as a household cleaner. It is formed when sodium reacts with carbon dioxide and water.

2Na + CO2 + H2O → 2NaHCO3

Na2CO3-NaHCO3: Sodium bicarbonate (NaHCO3) is a component of sodium carbonate (Na2CO3). When sodium carbonate is dissolved in water, it forms sodium bicarbonate.

Na2CO3 + H2O → 2NaHCO3

In summary, sodium (Na) reacts with sodium hydroxide (NaOH) to form sodium oxide (Na2O) and hydrogen gas (H2). Sodium reacts with carbon dioxide (CO2) and water (H2O) to form sodium carbonate (Na2CO3) and sodium bicarbonate (NaHCO3). Sodium carbonate can also be converted into sodium bicarbonate by dissolving it in water.
