Question

a student studied reaction of Zinc and sodium carbonate with dilute HCl and diluted NaOH respectively write the chemical reaction for the result obtained by him

Answer 1

I hope,

it is right reactions,

thanks

Answer 2

Answer: The reactions are given below.

Explanation:

We need to write the reaction of Zinc with dilute HCl and with dilute NaOH and the reaction of sodium carbonate with dilute HCl and dilute NaOH.

• Reaction of Zinc metal with dilute HCl and dilute NaOH:

With HCl: It will produce zinc chloride and release hydrogen gas.

$Zn+2HCl(aq.)\rightarrow ZnCl_2(aq.)+H_2(g)$

With NaOH: this metal will produce a salt named as sodium zincate and will release hydrogen gas.

$Zn(s)+2NaOH\rightarrow Na_2ZnO_2(aq.)+H_2(g)$

• Reaction of sodium carbonate with dilute HCl and dilute NaOH.

With HCl: It will produce a salt named as sodium chloride and release carbon dioxide gas.

$Na_2CO_3(s)+2HCl(aq.)\rightarrow 2NaCl(aq.)+H_2O(l)+CO_2(g)$

With NaOH: As, both the compounds are bases, hence no reaction will take place between them.

$Na_2CO_3(s)+NaOH(aq.)\rightarrow \text{No reaction}$
