Nitric acid - Wikipedia

Reactions with metals. 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 (Magnesium nitrate)

Type of Reactions With Copper & Nitric Acid | Sciencing

The reactions between copper and nitric acid are examples of oxidation-reduction reactions, where gaining electrons reduces one element and losing them oxidizes the other. Nitric acid is not only a strong acid, it is an oxidizing agent. Therefore, it can oxidize copper to Cu+2.

Balanced equation for Zinc (Zn) and Nitric Acid (HNO3

Apr 07, 2012· A salt is the product of an acid-base reaction. A salt consists of the ion (positive ion) of a base and the anion (negative ion) of an acid. You can make Zn(NO3)2 by reacting Zn(OH)2 (base) with HNO3 (acid) to produce Zn(NO3)2(aq) and water. Oxides and hydroxides are not salts. A metal hydroxide is a base, and a metal oxide is a basic anhydride.

inorganic chemistry - Why does copper react only with

How would you balance: Al(s) + HNO3(aq) --> Al(NO3)3(aq

Nov 10, 2015· 2Al + 6HNO_3 -> 2Al(NO_3)_3 + 3H_2 Most students are reluctant to double the beginning compound/element. Don''t be afraid to. A helpful tool is to write out each element and count up how many of them are on each side. Then edit those amounts each time WITHOUT doubling back on yourself. If you just changed the nuer to match the other side, leave it and change something else …
