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.

no all metals do not react with hydrochloric acids

No. First of all, the metal does not dissapear. When a a metal reacts with an acid it forms a corresponding salt, which usually then dissolves. Second, whther or not a reaction occurs depends on both the acid and the metal. Most metals will not react with a dilute weak acid. Some metals will not even react with most strong metals. Gold, platinum, and some platinum group metals will not react with acid except for aqua regia, a special mixture of hydrochloric and nitric acid. Ruthenium will not react with acid at all.

No, inert metals as Gold, Platinum and Palladium do not react with hydrochloric acid.

No, there are many metals which do not react with acid. Metals from copper downwards in the reactivity series do not react with acids (though you can get a different sort of reaction with concentrated oxidising acids). In addition, reactions which produce an insoluble salt, such as lead and dilute sulfuric acid, react only sluggishly. Some metals have a coherent oxide coating which prevents reaction with dilute acids, e.g. aluminium, and others quickly develop such a coating in concentrated nitric acid.

metals react with some acid

Many metals react with acid to liberate hydrogen, and form metal ions. The metal is oxidised.

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

All alkali metals (group 1) and most earth-alkali metals (group 2)

Metals whose surfaces are "passivated" by for example the formation of an insoluble oxide do not react with acid. An example is aluminium which is resistant to dilute acid.

metals which dont react with water or acid are called unreactive metals

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.

A metal that does not react to acid, oxygen or water does not exist.

Many. All the alkali metals will react explosively with it. All the alkaline earths will also react extremely vigorously. Group 3 metals from Al and below will and many transition metals do also. Copper, silver and Gold do not.

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.

Home/Sitemap · you are here: Forum => letter 18515 Acid and metal reaction++Q. When an acid is added to a metal, what kind of reaction is produced?A. Some acids react with some metals and not all acids react with all metals. It all depends on what is reacting with what. However, assuming there is a reaction, the acid will dissolve the metal to produce the metal salt of that acid; at the same time it will produce hydrogen gas. ie 2H+ + M = 2M+ + H2

Lots of metals will react with dilute hydrochloric acid; anything above hydrogen in the activity series should do so.

Because metals are often very reactive, as are acid.

Hydrogen gas. (But this is not with all metals as some like gold do not react with acid)

Yes, tin will react with sulphuric acid as it is reactive enough. Metals which are higher than hydrogen in the reactivity series will react with sulphuric acid.

Many acids will react with bases and, depending on the acid, some metals.

most metals do with the exception of gold, platinum, and rhenium.

there is no reaction when you add the two metals as metals cannot react with other metals metals can only react to acid etc.

Metals like sodium, magnesium, zinc and iron can react with sulphuric acid. However, less reactive metals like copper and gold do not.

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.
