Hint: Acids are generally those substances which have pH value less than 7, turn blue litmus paper into red and have sour taste rather than these the main property of an acid it is capable of donating a proton and also we can say that it is capable of forming a covalent bond.

Complete answer:
Nitric acid is a highly corrosive mineral acid represented by the chemical formula $HN{{O}_{3}}$ and the pure compound is generally colorless in nature but the older sample gets turns into yellow color due to decomposition into oxides of nitrogen and water.
Other given compound is sulfuric acid represented by the chemical formula ${{H}_{2}}S{{O}_{4}}$ and this is also known by the name vitriol and acts as a mineral acid composed by hydrogen, sulfur and oxygen. It is colorless in nature, has no odor and viscous liquid.
Mixture of conc.$HN{{O}_{3}}$ and conc. ${{H}_{2}}S{{O}_{4}}$ is known as nitration mixture and the reaction between these two can be shown as follows:
\[{{H}_{2}}S{{O}_{4}}+HN{{O}_{3}}\to N{{O}_{2}}+HS{{O}_{4}}^{-}+{{H}_{2}}O\].
During the reaction nitro group and anion i.e. those ions which are negatively charged here anion \[HS{{O}_{4}}^{-}\] are present and water molecules are produced as a product.
A nitrating mixture is defined as the mixture of concentrated nitric acid and sulfuric acid in 1:1 ratio and this type of reaction is used in the nitration of organic substances like aromatic compounds.

Note:
Mostly all of the mineral acids form hydrogen ions and conjugate bases when dissolved in water. Mineral acids range from superacids i.e. strong acids to very weak acids. These are soluble in water and insoluble in organic solvents.
