Question

For the reaction: h2nnh2 (aq) + h2o(l) ⇌ h2nnh3+(aq) + oh- (aq) determine the conjugate base of the acid?

Answer 1

The conjugate base in this reaction is the hydroxide ion OH⁻

Step-by-step explanation:

The reaction is:

NH₂NH₂ + H₂O ⇄ NH₂NH₃⁺ + OH⁻

In the reaction it can be seen that the water (H₂O) is acting as an acid, because it is donating its proton to compound H₂NH₂, so, in conclusion, the conjugate base in this reaction is the hydroxide ion (OH⁻)

Answer 2

In this reaction, water acts as the base and donates a proton to hydrazine (H2NNH2). Hydrazine becomes protonated: [N2H5]+ And thus hydrazine in this reaction is actually a base. The conjugate base of the acting acid H2O is OH- (hydroxide ion).
