If a metal electrode is used as the anode, the metal atoms may also give out electrons to form metal ions, i.e., the metal electrode may compete with the anion in giving out electrons. For example, if copper electrode is used as the anode in the electrolysis of copper sulfate solution, the copper electrode becomes thinner and thinner.

Reactions of hydrochloric sulfuric nitric acids with metals …
REACTION OF ACIDS WITH METALS General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process. e.g. the grey-silvery solid zinc dissolves in hydrochloric acid with effervescence to evolve hydrogen gas and leave a colourless solution of the salt zinc chloride.
Nitrogen Compound Precursors - energeticchemical
Or Ca(NO3)2 can be mixed with 30%H2SO4, precipitating CaSO4 and leaving 30%HNO3 in solution. This can react with metal, giving off nitric oxide, that reacts with air to make NO2. You would only want to react it with limited air, so there will not be any extra O2 in your NO2.

2020/8/14· For the reaction between Cu(s) and dilute HNO3(aq), it produces NO(g) not NO2(g). 2. To use half reactions to balance equations, you need to find the reducing agent and its products to make the oxidizing half reaction and to find the oxidizing agent and its products to make the reducing half reaction.

Coination Reaction of a Metal and Oxygen Gas A metal and oxygen react to produce a metal oxide. (a) Zinc is a metal with a predictable charge, that is, Zn 2+. The formula of zinc oxide is ZnO. The balanced equation for the reaction is (b) Chromium is a 3+.
Reaction between tin and nitric acid? | Yahoo Answers
2009/7/16· As you say, the hydrogen (and some of the oxygen) in HNO3 ends up as H2O. Presumably, the Sn finally ends up as Sn(NO3)2, because SnO is a basic oxide. The brown gas is NO2. This might be made directly, or the reaction might make NO, which reacts with

Nitric acid - Wikipedia
Nitric acid (HNO3), also known as aqua fortis (Latin for "strong water") and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water
