Answer = B = Neutrons and Mass Number

Isotopes 
are defined as those atoms which have same atomic number but different atomic masses.

Atomic mass is basically the number of protons and neutrons present in an atom.

Atomic number is the number of protons present in an atom.

So, in isotopes the number of protons are same but the number of neutrons vary due to which atomic masses also vary.
In given three isotopes, all have same number of protons but different number of neutrons.
i.e.
H-1 = 1 P + 0 N = 1 u (Proton)
H-2 = 1 P + 1 N = 2 u (Deuterium)
H-3 = 1 P + 2 N = 3 u (Tritium)

Hence, it is clear that the number after H shows a change in number of neutrons and mass number.

what is the purpose of adding concentrated phosphoric acid to the reaction mixture in the synthesis of aspirin
agasfer [191]

Concentrated phosphoric acid is added to the reaction mixture in the synthesis of aspirin to maintain the acidic environment and to keep the reagents protonated.

<h3>What is the phosphoric acid?</h3>

Phosphoric acid is an inorganic acid with the molecular H₃PO₄.

Its a triprotic acid which means that one molecule of the acid produces 3 molecules of hydrogen ions.

Phosphoric acid is important for many laboratory as well as industrial uses. It can be serve as buffer in living organisms.

It also used in the synthesis of aspirin.

The synthesis of aspirin requires an acidic environment. Therefore, concentrated phosphoric acid is added to the reaction mixture in the synthesis of aspirin to maintain the acidic environment and to keep the reagents protonated.

In conclusion, Phosphoric acid ensures an acidic environment in the synthesis of aspirin.
