Question
Name two alkalies that can displace hydrogen. Give balanced equations for the same. Why are the metals you have used considered to have a unique nature?
Solution
NaOH and KOH
Zn + 2NaOH → Na2ZnO2 + H2
Zn + 2KOH → K2ZnO2 + H2
Metals such as zinc, lead, and aluminium have a unique nature. They react with acids and can even react with hot alkalis to form hydrogen and soluble salt.
