Hydrogen gas is odorless, colorless, and has no taste. A hydrogen flame is nearly invisible because it emits light in the (invisible) ultraviolet spectrum.
Nothig to see ! Hydrogen is colorlees, odorless, with no taste. Also the flame is not very visible.
You put the gas in a tube and then put a lit wooden stick in it, if it pops it's hydrogen
it will burn with a pop noise
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.
A gas with one proton would be hydrogen gas (H2), which consists of two hydrogen atoms, each with one proton.
I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
Pure hydrogen gas is actually colorless and odorless in its natural state. The blue color you might associate with hydrogen gas is usually due to a flame or spark produced when hydrogen gas combusts with oxygen.
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.
When dilute acid, such as hydrochloric acid, reacts with magnesium, it produces magnesium chloride salt and hydrogen gas. You would see bubbles of hydrogen gas being released as a result of the reaction.
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
The solute in this case would be the hydrogen gas, as it is being dissolved or absorbed into the palladium. Palladium has the ability to absorb large amounts of hydrogen gas through a process known as hydrogen absorption.
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
