Which metals do not react with sulphuric acid?
Explanation: Copper is the only metal which does not react with dilute sulphuric acid.
Which metals do not react with acids?
Metals like gold,(Au) silver (Ag) do not react with any of the acids or oxygen. Hence they are called noble metals. However, aqua regia (a mixture of HNO3 and HCl ) can dissolve gold and silver.
Which metal does not react with HCl?
– Therefore the metals which do not react with dilute hydrochloric acid are copper and mercury.
Which metal does not react with hydrochloric acid while it reacts with sulphuric acid?
The correct answer is Copper. Copper does not react with dilute hydrochloric acid even on heating but reacts with sulphuric acid.
Which metal do not give h2 with HCL?
Detailed Solution The correct answer is Silver. The metal does not give H2 on treatment with dilute HCL is Ag.
What metals react with sulfuric acid?
Dilute sulfuric acid reacts with metals higher than hydrogen in the reactivity series to form sulfate salts and hydrogen gas. Note the metal reactions are different with concentrated sulfuric acid. Iron is cleaned free from rust prior to coating with tin to form tinplate and with zinc to form galvanized iron.
What metal does not react with nitric acid?
Some precious metals, such as pure gold and platinum-group metals do not react with nitric acid, though pure gold does react with aqua regia, a mixture of concentrated nitric acid and hydrochloric acid.
Which metal do not give h2 with HCl?
Does copper react with sulphuric acid?
Copper reacts with hot and concentrated sulphuric acid to form copper sulphate, sulphur dioxide gas and water.
Why copper does not react with hydrochloric acid but react with sulphuric acid?
The chemical potential of copper is insufficient to liberate elemental hydrogen from the compound in which the oxidation state of hydrogen is +1. Thus, copper does not react with dilute sulphuric acid, liberating hydrogen.
