The major product of the reaction is potassium hydrazide (KNNH₂).
What is potassium hydrazide ?
The reaction between hydrazine (NH₂NH₂) and potassium hydroxide (KOH) results in the formation of potassium hydrazide (KNNH₂) and water (H₂O).
The balanced chemical equation for this reaction is:
NH₂NH₂ + KOH → KNNH₂ + H₂O
So, the major product of the reaction is potassium hydrazide (KNNH₂).
