Question

write the balance equation of the reaction of zinc with dilute hydrochloric acid and sodium hydroxide solution

Answer 1

Answer:

Dilute HCl: Zn reacts with HCl and form zinc chloride with evolution of hydrogen gas. ... NaOH solution: Zinc reacts with NaOH solution and form sodium tetrahydroxidozincate and hydrogen gas. Zn + 2 NaOH + 2 H2O → Na2[Zn(OH)4] + H2. Question.

Answer 2

Zinc + Hydrochloric acid:

• Zinc reacts with dilute hydrochloric acid to form zinc chloride salt along with the evolution of hydrogen gas.
• In this reaction, hydrogen gas can be collected through a collecting glass tube.
• The reaction is:

$Zn+2HCl$ → $ZnCl_{2}+H_{2}$

Zinc + Sodium hydroxide:

• Zinc reacts with sodium hydroxide solution to give a complex compound called sodium zincate and hydrogen gas.
• Hydrogen gas is formed in the reaction which can be collected.
• The reaction is:

$Zn+2NaOH$ → $[Na_{2}ZnO_{2}]+H_{2}$
