Zinc reacts with hydrochloric acid to form :a)Hydrogen gasb)Zinc Chloridec)both Zinc Chloride & Hydrogen gasd)Oxygen gasCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Zinc is a metal and metal reacts with dilute acids to form metal salts and liberate hydrogen gas. Here Zn + 2HCl = ZnCl2 + H2 where Zinc chloride is metal salts and Hydrogen is evolved

Answer

Reaction of Zinc with Hydrochloric Acid
Zinc reacts with hydrochloric acid to form zinc chloride and hydrogen gas. This reaction is a classic example of a single displacement reaction, where a more reactive metal (zinc) displaces a less reactive metal (hydrogen) from its compound (hydrochloric acid).

Chemical Equation
The chemical equation for the reaction between zinc and hydrochloric acid is:
Zn + 2HCl → ZnCl2 + H2

Formation of Zinc Chloride
Zinc chloride (ZnCl2) is a white crystalline solid that forms when zinc reacts with hydrochloric acid. It is a salt that is soluble in water and is commonly used in various industrial processes.

Formation of Hydrogen Gas
Hydrogen gas (H2) is produced as a byproduct of the reaction between zinc and hydrochloric acid. The hydrogen gas is released as bubbles and can be observed as effervescence during the reaction.

Overall Reaction
The overall reaction between zinc and hydrochloric acid can be summarized as:
Zinc + Hydrochloric Acid → Zinc Chloride + Hydrogen Gas
In conclusion, when zinc is added to hydrochloric acid, it forms zinc chloride and hydrogen gas. This reaction is a common experiment in chemistry labs and demonstrates the reactivity of metals with acids.
