Question
secondary 4 | Chemistry
One Answer Below
Anyone can contribute an answer, even non-tutors.
Why is the answer D though?
Same for C since the N in NO3 disappeared on the products side.
HNO3 + NaOH → NaNO3 + H2O
In dilute nitric acid,
HNO3 dissociates in water to yield H+ and NO3- ions.
The H+ ions (hydrogen ions or otherwise known as protons, since H atoms have no neutrons and so H+ ions are effectively just lone protons) are what makes the solution acidic.
In aqueous sodium hydroxide,
NaOH dissociates in water to yield sodium ions (Na+) and hydroxide ions (OH-)
The hydroxide ions are what makes the solution basic/alkaline .
So , the H+ and OH- ions react to form the neutral H2O (water molecules)
H+ + OH- → H2O
Hence the term 'neutralisation'
The Na+ and NO3- ions do not take part in neutralisation and are called spectator ions.
