answer this che question please
compare dil solute of HCl and NaOH with respect to a) action of litmus solution (blue/red) b) reaction with Zn c) reaction with each other
Answers
Answer:
Given material is an acid that is HCl(Hydrochloric Acid) and a base that is NaOH(Sodium Hydroxide).
(a) Action of litmus paper
A litmus paper helps in identifying whether a material is an acid or a base or neutral substance.
Here, we are given with an acid - Hydrochloric Acid, hence, a red litmus paper will remain red where as a blue litmus paper will turn red.
With the base - Sodium hydroxide, red litmus paper will turn to blue and blue litmus paper will remain blue.
(b) Reaction with Zn
Zinc (Zn) is a metal.
Now, when zinc will react with an Acid :
Zn + 2HCl —> ZnCl2 + H2
Here, zinc chloride is formed along with hydrogen gas.
Now, when zinc will react with the base :
Zn + NaOH —> Na2ZnO2 + H2
Here, sodium zincate is formed along with hydrogen gas.
(c) Reaction with each other
Here, we have an acid and the other material as a base.
When both the materials react with each other that is an acid reacts with a base, this reaction is called neutralisation reaction.
The equation will be :
HCl + NaOH —> NaCl + H2O
Here, a salt that is NaCl or sodium chloride is formed along with water.
