Copper is less reactive than hydrogen (look at the reactivity series), so will not take the place of hydrogen in an acid to form a salt and hydrogen.

Metals which are more reactive than hydrogen will take the place of hydrogen to form a salt + hydrogen gas.

For example: Magnesium + hydrochloric acid --> magnesium chloride + hydrogen

All metals do not react with acids to produce hydrogen gas.Only those metals which lie above hydrogen react with acids to produce hydrogen gas.Whereas copper, silver, gold, and platinum do not react with acids to produce hydrogen.


Metals react with acid to produce hydrogen gas. Water reacts with acid to produce hydrogen ions. Electric current reacts with acid to produce hydrogen gas.


copper and hydrochloric acid do not react, however zinc and hydrochloric acid let of hydrogen (a fume). x


No. Copper will not react with most acids. It will react with nitric acid to produce nitrogen dioxide. Gold and platinum will not react with nitric acid but will react with aqua regia, a mixture of hydrochloric and nitric acids to produce nitrogen dioxide and some nitric oxide. Rhenium does not react with acid at all.


Copper does not produce hydrogen when reacted with sulfuric acid. It may react with concentrated H2SO4 in order to undergo a red-ox reaction.


There are 3 metals that react with acid to produce hydrogen. They are Zinc, Iron, and Magnesium.


Copper will not react with sulphuric acid, because copper is not reactive enough. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.


No, as copper is below Hydrogen in the reactivity series


No, copper is not reactive enough. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.


all those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc. ^^ He is incorrect. All metals, one or another, will react with some acids to produce Hydrogen Gas. -He mentioned Copper and Silver. Silver and Copper will react with Nitric Acid giving off Hydrogen and NitroDioxide Gas. He mentioned Gold and Platinum. Gold and Platinum will react with Aqua Regia (A mixture of Hydrogen Chloride and Nitric Acid) giving off Nitric Oxide, Nitrogen Dioxide, and Hydrogen gas. All metals will react with FluoroAntimonic Acid, Xenic Acid, or any other super acid to give off hydrogen gas and other gases as well.


Sorry, copper does not react with sulphuric acid because it is not reactive enough to do so. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.


No, copper is not reactive enough to do so. Only metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.


Nitric acid is an oxidising acid and copper will dissolve in concentrated nitric acid forming copper nitrate and liberating hydrogen gas.


Sorry, copper does not react with hydrochloric acid as it is not reactive enough to do so. Only metals above hydrogen in the reactivity series will react with dilute acids.


Concentrated sulfuric acid will react with copper giving sulfur dioxide and copper inns. Dilute acid doesn't show any reaction as copper metal cannot displace electrons from hydrogen.


An acid will not produce hydrogen gas by itself, but acids can produce hydrogen when they react with other things. For example, if hydrochloric acid is put in contact with zinc, the chlorine in the acid bonds with the zinc, and the hydrogen is released as a gas.


'You will get copper sulfate and hydrogen gas. Cu(SO4) + H2 ^This answer is incorrect, copper does not react with dilute sulphuric acid, as it does not displace the hydrogen (H2) from Sulphuric acid. This is because Hydrogen is more reactive than copper.


Almost any acid will react with magnesium to produce hydrogen.


I only know 3 metals that react with acids to produce hydrogen. They are Zinc, iron and magnesium. There are 3 acids which react with them: and It will produce hydrogen gas which is the lightest known gas and is flammable :)


Copper is unreactive and will not react with acids to liberate hydrogen gas. However it may react if concentrated and oxidising acids are used.


An acid reacts with metal to produce hydrogen gas.


By definition metals above hydrogen should react with acids to produce hydrogen and a metal salt when mixed, but carbonic acid is a weak acid and it won't react as much like sulfuric acid.


No. Acid will generally react with metal to produce hydrogen. In order to produce carbon dioxide, and acid must react with a carbonate.


No. Copper does not react with hydrochloric acid
