What liberate hydrogen gas when treated with dilute HNO3?

Zinc liberates hydrogen gas when treated with dilute HNO3.


What is the word equation for the preparation of hydrogen?

The word equation for the preparation of hydrogen gas is: metal + acid → salt + hydrogen gas. For example, when hydrochloric acid reacts with zinc, it produces zinc chloride salt and hydrogen gas.


Why calcium is not used in the lab preparation of hydrogen?

Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.


Why potassium is not used in preparation of hydrogen?

Potassium is not used in the preparation of hydrogen because it is a highly reactive metal that reacts vigorously with water to form potassium hydroxide and hydrogen gas. This reaction can be dangerous due to the high reactivity of potassium, making it unsuitable for the controlled generation of hydrogen gas. Sodium is often used instead as it reacts less violently with water.


Why lead is not used for preparation of hydrogen?

Lead is not used for the preparation of hydrogen because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are commonly used because they react more readily with acids or water to produce hydrogen gas. Lead's lack of reactivity makes it unsuitable for this purpose.

Why is nitric acid in the dilute form not used in the laboratory preparation of hydrogen from metals?

It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.


Reacts with a metal to form hydrogen gas and a salt?

A strong acid like nitric (HNO3), hydrochloric (HCL), sulfuric (H2SO4) to name a few.


Mg plus HNO3 equals what?

When magnesium (Mg) reacts with nitric acid (HNO3), it produces magnesium nitrate (Mg(NO3)2) and hydrogen gas (H2).


Why nitric acid is not used in lab preparation hydrogen?

Nitric acid is a strong oxidizing agent that can react violently with reducing agents such as hydrogen, leading to potential explosions. This makes it unsafe to use nitric acid in the lab for the preparation of hydrogen gas. Preferred methods for generating hydrogen gas typically involve non-oxidizing acids like hydrochloric acid reacting with a metal like zinc.


What acid would be used if sodium nitrate and hydrogen are formed?

If it was a reaction between sodium hydroxide and an unknown acid the acid would be nitric acid (HNO3)


Another reagent that could be used in place of HCL to precipitate cations of the silver group?

Another reagent that can be used to precipitate cations of the silver group is hydrochloric acid (HCl).


What type of gas was used in zeppelins?

Zeppelins used hydrogen gas as the lifting gas to make them buoyant in the air.
