Which of the following does not liberate hydrogen on reacting with acids?
The correct answer is Cu. Copper (Cu) does not liberate H2 when it reacts with acid. Cu is least reactive than Hydrogen. So it cannot displace hydrogen from acid.
Which one of the following will not liberate hydrogen?
Therefore, \[M{n^{2 + }}\] does not liberate hydrogen gas on reaction with dilute acids. Hence, the option is (B) \[M{n^{2 + }}\], it does not liberate hydrogen gas on reaction with dilute acids.
What liberates hydrogen gas on reacting with both acids and bases?
If you try each of the elements with a acid i.e. HCl and a base i.e. NaOH, you will youself come to a result that Na or sodium liberates both hydrogen gas with acid and base.
How would you show that metals react with acid to liberate hydrogen?
try to place a burning candle in the gas,u will hear a pop sound.so,this gas is hydrogen. HYDROGEN BURNS WITH A POP SOUND.
Which element after reacting with acids liberate hydrogen gas and can displace lead and tin from their salt solution?
Explanation: nickel is more reactive tan both tin and lead hence can replace them from their salt solution gold copper and mercury are all less reactive than lead and tin.
Which metal can liberate hydrogen gas with an acid as well as with the base?
(D). mercury. Hint: The metal that gives hydrogen gas upon treatment with both acid as well as base will be the one that can react with both acid as well as base.
Which of the following metals produces hydrogen on heating with acids as well as with alkalies?
Zn is amphoteric metal and reacts with acids as well as alkalies to give hydrogen gas.
Which metals do not liberate gas on reaction with acids?
Copper (Cu) cannot liberate H2 from acids.
Do acids liberate hydrogen gas?
Acids react with active metals to liberate hydrogen.
Which metals among the following can displace hydrogen from acids?
So, aluminium, and magnesium, or any other metal placed above hydrogen can be considered as an example of the metals that displace hydrogen from dilute acids; and mercury, and silver are the metals which will not displace hydrogen.
Which of the following metals can displace hydrogen from acids?
the ans. is magnesium and zinc.
Which metals can react with both acids and bases?
Such metals that can undergo reaction with both acids and bases are known as amphoteric metals. Some examples of such metals are zinc (Zn) and aluminium ( Al).
