Hydrogen is not a corrosive gas; but the hydrogen absorbed in metals may lead to the formation of metal hydrides and to embrittlement.
Take a tube, put a piston in it, seal off both ends of the tube, and use a liquid, or gas to put pressure in and remove pressure from the tube. As the fluid or gas goes in the tube, the pressure pushes the piston out. As the pressure is released, the piston can recede.
As this relates to EE, the electrons are already in there.
One of the problems with heat recovery boilers behind incinerators of solid,liquid or municipal solid wastes is high temperature corrosion associated with the formation of complex eutectics which have a low melting point and deposit as slag on boiler heating surfaces.This is difficult to get rid of and results in high temperature corrosion,fouling problems and consequent higher exit gas temperature from the boiler and consequent lower steam generation.Another concern in these applications is the presence of corrosive gases such as chlorine and hydrogen chloride,which corrode the boiler tubes,particularly those operating above 800 F,resulting in tube thinning and failure
To limit the current through the lamp when the gas ionises and conducts.

If the gas in the test tube is hydrogen, the substance inside would be hydrogen gas since the gas in the tube is hydrogen itself.
Most acids are sour and corrode metals.
When hydrogen gas is produced in a chemical reaction, it displaces the water in the measuring tube since hydrogen is less dense than water. As a result, the water level in the tube rises as the lighter hydrogen gas occupies the space previously filled by water.
When rhubarb reacts with steel cans, the gas formed is hydrogen gas. This reaction occurs due to the acidic nature of rhubarb, which can corrode the steel cans and release hydrogen gas as a byproduct.

You put the gas in a tube and then put a lit wooden stick in it, if it pops it's hydrogen
Hydrogen gas (H2) is not very soluble in water, and so it will displace the water in the container, thus making the level rise.
To check if a gas is hydrogen, you can perform the "squeaky pop" test. Collect a small sample of the gas in a test tube and ignite it with a flame; if it produces a squeaky pop sound, it is likely hydrogen gas. Additionally, you can use a flame test in a controlled laboratory setting to see if the gas burns with a pale blue flame, characteristic of hydrogen.
It is captured in an upside down test tube or a gas collecting tube.
You can test for the evolution of hydrogen gas by collecting a gas sample from the reaction using a gas syringe or inverted test tube. You can then test this gas by lighting a flame at the mouth of the container to see if it ignites with a 'squeaky pop' sound characteristic of hydrogen gas. Alternatively, you can use a glowing splint to see if it reignites in the presence of hydrogen gas.
A Bourdon tube pressure gauge is used to measure the pressure of a gas or liquid in a system. When the pressure increases, the tube straightens, and this movement is indicated on the gauge's dial. Bourdon tube gauges are commonly used in various industries to monitor and regulate pressure in systems to ensure safe and efficient operation.
Light a wooden splint and hold it in some of the unknown gas(which is supposedly hydrogen). If there is a loud "pop" sound, then it is hydrogen. there is a very quick and simple way to do this you have to trap the gas in side a test tube but make sure it is half full of water, trap the gas and if when you turn the test tube upside down and the water stays in the same place the bottom of the tube (which would now be top) then you have "H" HYDROGEN
