The shell sat in the remaining HCl solution (still 5.7M) over the weekend with no visible reaction but the solution slowly turned green and the copper dissolved completely by the following Friday. Concentrated hydrochloric acid is added, changing the solution back to green. All metals do not react with the same rate. VAT no. Cu does not react with dil Sulphuric acid (H2SO4) or dil hydrochloric acid (HCl). The zinc reacted quickly and by the next day the penny had been converted into a hollow copper shell. Copper does not react with HCl acid, but copper oxide does react. Copper is too unreactive and cannot displace hydrogen from hydrochloric acid. 0 0. Although you should take a look at what Klaus said, copper does in fact react with hydrochloric acid, it just takes a week until all the copper is converted into copper chloride (green) and another week or so until it forms crystals and you can dissolve them in water to form copper chloride again (but depending on the amount of chloride it has, it'll be blue or green). Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Mismatch between my puzzle rating and game rating on chess.com.

Edited to include additional information from previous comments. But metal oxides are basic substances, and so they generally react with acids forming respective salt and water. It will also react with nitric acid to form oxides of nitrogen. MARTYN F. CHILLMAID / SCIENCE PHOTO LIBRARY. London As an example, a student of mine recently asked about this with regard to a penny. Normally, the reaction would produce a metal salt (here copper chloride) and hydrogen gas, but copper's low reactivity means that … In fact, copper would slowly dissolve in acid. I thought about mentioning the oxidizing acid aspect of HCl and air, but decided against it for simplicity's sake. hope that helps :) @permeakra Good point. So we … @IvanNeretin Indeed, but this takes a loooong time before the reaction is noticeable, at least with the acid concentrations I've used for this (several days.) Thanks for contributing an answer to Chemistry Stack Exchange! Hydrochloric and phosphoric acid don't oxidize metals well and won't dissolve copper. The solution can change color several times by alternating the addition of water and hydrochloric acid. Indicators are used to determine whether a solution is acidic or alkaline.
