NEETChemistryHydrogen
What is the chemical equation for the preparation of dihydrogen using zinc and dilute hydrochloric acid?
Options
- AZn + 2H 2 O → ZnO + 2H 2
- BZn + 2H+ → Zn2+ + H 2
- CZn + 2H 2 O → Zn(OH) 2 + H 2
- DZn + HCl → ZnCl 2 + H 2
Correct answer
B. Zn + 2H+ → Zn2+ + H 2
Step-by-step solution
The chemical equation for the preparation of dihydrogen using zinc and dilute hydrochloric acid is given as Zn + 2H+ → Zn2+ + H 2 .
