Question

which of the following occur as a solution in the following reaction:-

zinc + sulphuric acid+ zinc sulphate + hydrogen


(a) zinc.
(b) hydrogen .
(c) sulphuric acid.
(d) sulphuric acid and zinc sulphate .​

Answer 1

Answer:

zinc reacts with sulphuric acid and become zinc sulphate .

Answer 2

(b) hydrogen is released in this reaction.

Type of reaction:

• The response of zinc with weakening sulphuric acid is a non-metal displacement redox response.
• This sort of redox response includes hydrogen removal from acids by a metal.
• In the uprooting response, more receptive metal dislodges less responsive metal.

Can $Zn$ replace hydrogen?

• In the electrochemical series, the position of $Zn$ and iron is above hydrogen whereas copper and mercury are put beneath hydrogen.
• Since zinc is more responsive than hydrogen it uproots hydrogen in weakening sulphuric corrosive.

Release of hydrogen:

• In these responses, metal iotas uproot hydrogen from acids.
• These responses are utilized to plan hydrogen gas $H_{2}$ in the research facility.
