Nitric acid ({eq}HNO_3 {/eq}) is a strong acid as it has a high acid acid dissociation constant ({eq}K_a {/eq}) of 23 (this can be obtained in a data booklet). In chemistry, there are seven "strong" acids. HNO3 (nitric acid) is a strong acid. What makes them "strong" is the fact that they completely dissociate into their ions (H + and an anion) when they are mixed with water. In chemistry, neutralization or neutralisation (see spelling differences), is a chemical reaction in which an acid and a base react quantitatively with each other. Strong acid may also be made indirectly from the weak acid by using extractive distillation with a dehydrating agent. This compound is a very powerful oxidizing agent and is widely used in nitration reactions that involve the addition of a nitro group to a given reactant. Every other acid is a weak acid.Because there are only seven strong acids, it is easy to commit the list to memory. 5. Nitric acid concentration processes use a dehydrating agent such as sulfuric acid or magnesium nitrate to enhance the volatility of HNO3 so that distillation methods can surpass the azeotropic concentration of nitric acid. All acids are weak acids except for the 6 strong acids: HCl, HBr, HI, HNO3, HCLO4, and H2SO4. Nitric Acid (HNO3 → H+ + NO3-) Nitric acid is a colorless, highly corrosive mineral acid. Yes, it is. Nitric acid is prominently used for nitration – adding a nitrate group to … Nitric Acid (HNO3) Nitric acid (denoted by the chemical formula HNO3), also referred to as the spirit of nitre and sometimes as aqua fortis, is an extremely corrosive mineral acid.
