(b) What would you observe when :
(1) Hydrogen chloride gas is passed through silver nitrate solution and
product formed is treated with excess of ammonium hydroxide.
(ii) Ammonia gas is passed through aqueous copper sulphate solution first in
little and then in excess quantity.
(111)During the electrolysis of copper sulphate solution using platinum
electrode
(iv)Concentrated sulphuric acid is added drop wise to the mixture of dilute
nitric acid and ferrous sulphate solution.
(v) When ammonia gas is passed through phenolphthalein solution
Answers
Answer:
1. A white precipitate of silver chloride will be formed when Hydrogen chloride gas is passed through silver nitrate.
2HCl+2AgNO
3
→2AgCl+2HNO
3
The reaction between AgCl and NH4OH will result in the products of Ag(NH3)
2
+
and Cl
−
ions.
AgCl+2NH

OH→Ag(NH3)

Cl+H

O
2. Blue colour solution
3. During electrolysis of aqueous copper sulphate solution using platinum electrodes, the blue colour of the electrolytic solution fades and towards the end of the process bubbles appear at the cathode
4. Sorry to say I did not no the ans 4. l can not help sorry
5.Three ways in which ammonia gas can be identified is:
It has a sharp characteristic odor
When a glass rod dipped in HCl is brought in contact with the gas white color fumes of ammonium chloride are formed
It turns moist red litmus blue, moist turmeric paper brown, and phenolphthalein solution pink.
