Question

Why calcium nitrate does not react with ammonium hydroxide?

Answer 1

क्योकि दोनो बेस है इसलिए यह रिएक्शन नही करते है

Answer 2

Here is your answer,

No precipitation occurs even with addition of excess of NH4OH.

This is because the concentration of OH- ions from the ionisation of NH4OH is so low that it cannot precipitate the hydroxide of calcium.

Hope it help you.
