When lead reacts with NaOH, a colourless salt X is formed along with hydrogen gas. Name the salt X.
Potassium plumbate
Sodium plumbate
Lead hydroxide
Lead oxide
Lead reacts with NaOH to form sodium plumbate (a colourless salt) and liberate hydrogen.
Pb+2NaOH→Na2PbO2+H2
Hot concentrated sodium hydroxide reacts with lead hydroxide to produce lead oxide, sodium oxide and water.
The salt formed when aluminium oxide reacts with potassium hydroxide is:
When zinc react with hot and concentrated NaOH, a colourless salt is formed. Name this colourless salt.
When an excess of sodium hydroxide is added to lead nitrate, a ____ precipitate of lead (II) oxide is formed.
When hot concentrated potassium hydroxide is added to lead, potassium oxide is obtained as the major product and hydrogen gas is liberated in the process.
