Zinc nitrate is usually prepared by dissolving zinc metal, zinc oxide, or related materials in nitric acid: Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2 ZnO + 2 HNO 3 → Zn(NO 3) 2 + H 2 O. These reactions are accompanied by the hydration of the zinc nitrate. The anhydrous salt arises by the reaction of anhydrous zinc chloride with nitrogen dioxide: [1]
Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Magnesium, manganese, and zinc liberate H 2: Mg + 2 HNO 3 → Mg(NO 3) 2 + H 2 Mn + 2 HNO 3 → Mn(NO 3) 2 + H 2 Zn + 2 HNO 3 → Zn(NO 3) 2 + H 2
Aqua fortis /spirit of nitre – nitric acid, formed by 2 parts saltpetre in 1 part (pure) oil of vitriol (sulfuric acid). (Historically, this process could not have been used, as 98% oil of vitriol was not available.) Aqua ragia /spirit of turpentine/oil of turpentine/gum turpentine – turpentine, formed by the distillation of pine tree resin.

Nitrates affect the nitrate‐nitrite‐nitric oxide pathway, in which nitrates are recycled in blood and tissue to produce nitric oxide — an important molecule for vascular health and blood flow.
The nitric acid and peroxide mixture oxidizes and dissolves any impurities on the inner surface of the container, and the deionized water rinses away the acid and oxidized impurities. [ 17 ] Generally, there are two main ways to passivate aluminium alloys (not counting plating , painting , and other barrier coatings): chromate conversion ...
Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [ b ] Aqua regia is a fuming liquid.
That means, “Whether it’s safe to take zinc every day as a supplement depends on how much zinc is in the supplement and how much you get from your diet,” says Haggans.
