Question

(a) What happens when zinc granules are heated with sodium hydroxide solution? Write equation of the reaction which takes place.
(b) What happens when bases react with non-metal oxides? Explain with the help of an example. What does this reaction tell us about the nature of non-metal oxides?

Answer 1

Answer:

a)when zinc reacts with sodium hydroxide it forms sodium zincate and hydrogen.

zn + NaOH--------->Na2ZnO2+H2

b)when non metal oxide reacts with bases it forms salt and water .

Ca (OH)2 + CO2------------>CaCO3 +H2O

it is similar to neutralisation reaction so non metal oxide are acidic in nature.
