Not much!
Some of it, a tiny amount, might bond to the water molecules, but as water already has its standard H2O composition, most extra hydrogen will simply bubble out, hydrogen being lighter than water.
For details and discussion of hydrogen bonding with water, see Related Links below these advertisements.
The solubility of hydrogen gas in water at 0oC is 0.0019 grams of hydrogen per kilogram of water. At 60oC, the solubility is 0.0012 grams of hydrogen per kilogram of water. That is a tiny amount that will dissolve in the water. The rest would simply bubble out as the previous answerer said. Also, most likely, the water would be already saturated with hydrogen since it was in contact with the atmosphere, which contains hydrogen; so unless you took steps to purge the hydrogen from the water to get water not already saturated with hydrogen, all of the added hydrogen would bubble out since the water would be already saturated with hydrogen.
Electrolysis breaks water into hydrogen and oxygen. When an electric current is passed through water, the water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode.
When hydrogen peroxide is mixed with boiled water, the hydrogen peroxide will decompose into water and oxygen gas. The heat from the boiled water can accelerate this decomposition reaction, causing the hydrogen peroxide to break down more quickly. This reaction is exothermic, meaning it releases heat energy as the oxygen gas is produced.
when hydrogen chloride is dissolved in water to form hydrochloric acid, the hydrogen chloride turns to HCL subscript 38 because of the water molecules. i also believe that they change from clear to a misty green colour but it may just be the result of a dirty test tube.
Water that contains hydrogen-2 instead of hydrogen-1 is called heavy water.
When copper chloride is put into water, it starts dissociating. The molecule of copper chloride breaks up to give a cuprous ion(Cu2+) and 2 Chloride ions(Cl-). The water molecules weakly dissociate to give hydrogen ions(H+) and Hydroxyl ions(OH-). The oppositely charged ions interact and form a weak bond known as hydrogen bond. This interaction results in the copper chloride dissolving in the water.
Hydrogen does not react with water
Potassium metal will react violently with water to form KOH and hydrogen gas. Due to the heat released by the reaction - the hydrogen gas will ignite. So: placing potassium in water will cause a fire!
Calcium reacts slowly with water. The reaction forms calcium hydroxide, Ca(OH)2 and hydrogen gas (H2).
water is left
Hydrogen is released in the atmosphere.
When you put a battery in water, it can cause a chemical reaction that releases hydrogen gas and can lead to the battery overheating or even exploding. This is because water can act as an electrolyte and allow the battery to discharge rapidly, which can be dangerous. It is important to never put a battery in water to avoid potential hazards.
Perchloric acid is dissociated in water.
A chemical reaction between oxygen and hydrogen occur.
The Hydrogen will burn fiercely with a lambent blue flame and water will be produced.
Water. When you put electrodes into water and pass a current, you produce hydrogen and oxygen gasses.
When a lit splint is put into hydrogen, it creates a squeaky pop sound as the hydrogen gas rapidly combusts with oxygen in the air, forming water vapor. This reaction is highly exothermic and releases a significant amount of energy in the form of heat and light.
A water solution is obtained.
