Question

Is NH_4F(aq)+NaOH(aq)→NaF(aq)+NH_3​ (g)+H_ 2 O(l) a gas evolution reaction?

a) Yes
b) No
c) It depends on temperature
d) It depends on pressure

Answer 1

No, the reaction NH4F(aq) + NaOH(aq) → NaF(aq) + NH3​(g) + H2O(l) is not a gas evolution reaction.

Step-by-step explanation:

No, the reaction NH4F(aq) + NaOH(aq) → NaF(aq) + NH3​(g) + H2O(l) is not a gas evolution reaction. In a gas evolution reaction, a gas is produced as one of the products. In this reaction, the only gas produced is NH3​(g), while NaF(aq) and H2O(l) are both aqueous solutions. Therefore, the correct option is b) No.
