Another reagent that could be used in place of HCL to precipitate cations of the silver group?
HNO3 which forms white precipitate..
What is the preparation of hydrogen?
The preparation of hydrogen gas is usually from a reduction of a compound containing hydrogen that is in the +1 oxidation state. This reduction is accomplished either electrically or chemically.
Is nitric acid an oxidising agent?
No. Hydrogen gas is generally a reducing agent.
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.
Why concentrated nitric acid is not used to prepare hydrogen gas?
Usually an active metal displaces hydrogen acids. But Nitric Acid is a very strong oxidizing agent i.e. it leads to addition of oxygen to another substancevery quickly . Thus, when hydrogen is formed due to the addition of a metal to nitric acid, it oxidises hydrogen into water. That is why concentrated nitric acid is not used in the preparation of hydrogen gas.

What gas is hydrogen?
Hydrogen gas is an extremely high explosive gas often used to make bombs...
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.
What does Magnesium combined with nitric acid make?
Magnesium (Mg) + Nitric Acid (HNO3) ---> Magnesium Nitrate (MgNO3) + Hydrogen gas (H) + Heat
Why nitric acid does not liberate hydrogen gas with most metals?
It is because HNO3 is a strong oxidising agent.So as soon as H2 is formed in the reaction between a metal and dilute nitric acid oxidises this hydrogen to water.
Why is hydrogen gas is not used in balloons?
Hydrogen is too flammable
What are some practical uses of hydrogen?
Some practical uses are that hydrogen is for fuel. That is a practical use for hydrogen. Hydrogen is the first element on the periodic table. It is the only element that doesn't have neutrons in it. Hydrogen is also the lightest of all elements.
What gas was in the Hindenburge?
Hydrogen gas was used to inflate the Hindenburg.
