Chemistry equations

Hello can anyone please explain for me how to know the right answer ?


The No3- ion combines with H+ in water to give HNO3 which is a pretty strong acid. NH4OH is not that strong a base.

Cl- also forms a strong acid but it’s neutralised by the strong base ie NaOH that’s formed.

Same with HClO4 neutralised by strong base in Ca(OH)2
