Chhavi Sharma 3 years, 1 month ago

This is because H+ ions are produced in the presence of water , the separation of H+ ions cannot occur in the absence of water. Hydrogen ions cannot exist alone but they exist after combining with water molecules.

"When non-metals react with acids Hydrogen gas do not evolve " WHY ?

Posted by Nitin Singh Mouni 3 years, 2 months ago

CBSE > Class 10 > Science

3 answers

Aditya Kharat 3 years, 2 months ago

No it doesn't evolve h2 gas because unlike metals, non-metals do not have a tendency to lose electrons but to gain electrons. ... Only those metals which are reactive than hydrogen will displace H2 from acids.

1Thank You

Tarun Tarun 3 years, 2 months ago

Non metal can not loose electron because they cannot lose electron so valency of hydrogen is not completed so hydrogen cannot be de attached from acid so non metal does not react with acids.
