Lithium silicide reacts explosively with nitric acid, producing nitrogen dioxide and silica. Such metals can be dissolved by using a combination of acids or a dilute nitric solution. When formed during acid-metal reactions, these compounds are usually referred to as salts. of nitric acid were poured onto 15 grams of lithium in an attempt to dissolve the metal, a small fire started in the flask. The experiment is done first on a smaller scale using test tubes (lesson 1 below), with no attempt to recover the salts formed. Many, but not all, metals react with acids. Concentrated nitric acid is a very strong oxidator capable of reacting with the noble metals such as copper or silver (not gold, however). When concentrated nitric acid is dropped on a copper disk in the bottom of a glass cylinder, a reddish-brown cloud of nitrogen dioxide gas is rapidly evolved. Reaction of cadmium with hypochlorite.

Another method to chemically generate gas is the oxidation of metals in acidic solutions. Cu + 4HNO 3 Cu(NO 3) 2 + 2NO 2 + 2H 2 O. Acids react with metals, bases and carbonates to produce salts. In this reaction, Zn is your base and nitric acid is obviously your acid, so if we see a "new" product at the end, we should probably call it a salt. For the Love of Physics - Walter Lewin - May 16, 2011 - Duration: 1:01:26. Most metals and alloys are oxidized by nitric acid; however, gold and platinum are not oxidized and some metals are passivated when attacked by concentrated nitric acid.

Nitric acid reacts with copper and produces different products according to its concentration. Special Case of Nitric Acid: Nitric acid does not react with metals in the same way as hydrochloric acid or sulphuric acid do. In a petri dish, –add 5 mol dm. A. Nitric acid is an oxidising acid. The method is particularly useful for copper, aluminium, chromium, cobalt, indium, iron, nickel, silver and thallium nitrate production. Copper metal and zinc metal react differently in the presence of certain acids. Pretty straightforward. Reactions of acids with metals. REACTION OF ACIDS WITH METALS. Aluminum and zinc do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults. But unlike the reaction between acids and bases, we do not get water. Picture of reaction: Сoding to search: Ag + 2 HNO3 = AgNO3 + NO2 + H2O. asked Aug 18 in p-Block Elements – II by Nilam01 (35.6k points) closed Aug 19 by Nilam01. The oxide which can be reduced by hydrogen is_____. Nitric acid(HNO3) is a strong oxidising agent. Nitrogen oxide pollution is a nuisance caused mainly by flue gases of power plants using fossile fuels and by the exhaust gases of internal combustion engines. View solution.
