State any one observation mixture of ammonium chloride and sodium hydroxide is heated
Answers
HELLO THERE!
You must know:
Ammonium salt + Alkali ------> Alkali salt + Water + Ammonia.
In your question, the ammonium salt is ammonium chloride and the alkali taken is sodium hydroxide, so the products formed are sodium chloride, water and ammonia gas is evolved.
Reaction:
NH₄Cl + NaOH -----> NaCl + H₂O + NH₃
Observation:
A pungent smelling gas is evolved (ammonia), which burns in air with a yellowish green flame.
Some tests:
When a rod dipped in HCl is brought near it, we get to see white fumes (due to formation of dense white fumes of NH₄Cl).
A reddish brown gas is evolved when the gas is reacted with oxygen with Platinum as catalyst, at 800°C. (First NO is formed, then NO + O₂ gives NO₂, which is reddish brown).
Thanks!
Answer:
When the mixture of ammonium chloride and sodium hydrochloride is heated than some new components are fromed ,those are ammonia,water,and sodium chloride.
Reaction for the observation is-
NH4Cl+NaOH --->NaCl+ H2O+NH3
Hope it's correct and helpfull
