The reaction between sodium hydroxide with zinc gives the product-

Correct option is C

The correct answer is (c) Sodium zincate.
· When sodium hydroxide (NaOH) reacts with zinc (Zn), it forms sodium zincate (Na2ZnO2) and releases hydrogen gas.
· This is an example of a reaction where a metal (zinc) reacts with a strong base (sodium hydroxide), and the reaction can be represented by the following chemical equation:
Zn+2NaOH+2H2O→Na2ZnO2+H2
In this reaction, zinc dissolves in the sodium hydroxide solution to form sodium zincate and hydrogen gas.
Additional Knowledge:
· Zinc oxide: This is incorrect. Zinc oxide (ZnO) forms when zinc reacts with oxygen, not sodium hydroxide.
· Reaction is not possible: This option is incorrect, as the reaction between sodium hydroxide and zinc does occur.
· Zinc hydroxide: Zinc hydroxide (Zn(OH)2) can form in reactions involving zinc and weak bases, but in this case, sodium zincate is the correct product.
