Acids have hydrogen. As in HCL or hydrochloric acid
H2NO3 is not a valid chemical formula. Nitric acid, which has the formula HNO3, is an acid.
If you meant HCl, Hydrochloric Acid, it is a strong acid and not a base. A way to tell if it is an acid is that it has an H+ in the chemical formula. Most of the time, if it is a base it has an OH- attached to the chemical formula, but this is not necessarily true for all bases.
The conjugate base of NH4+ is NH3. The formula for the conjugate base of an acid can be obtained by removing a proton (H+) from the acid molecule.
A base contain the anion (OH)- and an acid contain the cation H+.
An acid typically has hydrogen as the first element in its chemical formula, such as HCl for hydrochloric acid. A base will often contain hydroxide ion (OH-) in its formula, like NaOH for sodium hydroxide. The number of hydrogen ions and hydroxide ions can also indicate the strength of the acid or base.
When you add a base to an acid, they undergo a neutralization reaction to form water and a salt. The general chemical formula for this reaction is: acid + base → salt + water
HCl is hydrochloric acid HI is hydroiodic acid HF is hydrofluoric acid H2SO4 is sulfuric acid HNO3 is nitric acid HBr is hydrobromic acid HClO4 is perchloric acid
To identify a base from its chemical formula, look for hydroxide ions (OH-) in the formula. Bases typically contain hydroxide ions, which give them their characteristic properties.
2H + + SO4 2- <-> H2SO4 Sulfuric acid is the conjugate acid here.
HCl is hydrochloric acid and NaOH is sodium hydroxide a base.

The amount of base depends on the chemical formula of the acid.
