When NaOH is mixed with an unknown non-metallic oxide ‘X’, sodium carbonate is produced. Name the unknown substance X.
Sodium hydroxide reacts with carbon dioxide to give sodium carbonate and water.
2NaOH + CO2 → Na2CO3 + H2O
Base Non metallic Salt Water
When HNO3 is mixed with an unknown solution 'X', sodium nitrate is produced. Name the unknown substance X. HNO3 + X NaNO3 + H2O
When the concentrated aqueous solution of substance X is electrolysed, then NaOH, Cl2 and H2 are produced. Name the substance X. What is the special name of this process?
When a non-metal reacts with oxygen, it forms a non-metallic oxide. This non-metallic oxide when reacted with H2O, form a substance, ‘X’ with pH value less than 7. Select the correct option regarding the substance, ‘X’.
