Question

Ca(NO3)2 is dissolved in NH4OH Solution. State the observations.

Reference: ICSE chemistry class 10

Answer 1

I think the observation is :-
A precipitate of calcium hydroxide.

Answer 2

no precipitation occurs even in the excess of NH4OH.
this is because the concentration of  OH¬ ions from the ionisation of NH$OH is so low that it cannot precipitate the hydroxide of calcium..

or

the observation will be white ppt but it is insoluble in excess.
