Addition of 6 M HCl to which substance will NOT result
2 answers:
Addition of 6 M HCl to <u><em>NaNO₃</em></u> will not result in gas evolution
<h3>Further explanation </h3>HCl is a strong acid that is fully ionized in water
There are several reactions that involve reactions with HCl
- (A) Al
Aluminum is a metal element in the third period
Aluminum will react with acids such as HCl to produce hydrogen gas
Reactions that occur:
Al (s) + 3H + (aq) ⇒ Al³⁺ + 3/2H₂ (g)
- B) Zn
Zinc is a transition metal element
Zn reaction with HCl will produce hydrogen gas
Zn + HCl ⇒ ZnCl₂ + H₂
- C) K₂CO₃
Potassium carbonate is a salt produced from the reaction of potassium hydroxide with carbon dio/xide
HCl reaction with K₂CO₃
HCl + K₂CO₃ ⇒ H₂CO₃ + KCl
H₂CO₃ is a weak acid, will decompose into CO₂ and H₂O
H₂CO₃ ⇒ CO₂ + H₂O
So this reaction producing CO₂ gas
- (D) NaNO₃
Sodium nitrate is a salt
Reaction with HCl
HCl + NaNO₃ -> NaCl + HNO₃
produces no gas , NaCl salt and strong acid HNO₃
