∙ 7y agoWhen 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.
Hydrogen gas (H2) is not very soluble in water, and so it will displace the water in the container, thus making the level rise.
The dip in water in a test tube is known as the meniscus. It is caused by the surface tension of the water, which causes it to curve slightly at the edges of the container. When measuring liquids in a test tube, readings are typically taken at the bottom of the meniscus.
Liquid water rises higher in a narrow tube due to capillary action, where the water molecules are attracted to the walls of the tube. This effect is more pronounced in narrow tubes compared to wider tubes.
If the liquid in Tube A is connected to a vacuum pump and the pressure in the system is decreased, the liquid in Tube A will rise due to the reduced pressure in the tube allowing the liquid to travel upwards.
When burning hydrogen at the mouth of a test tube, it will produce a squeaky pop sound due to the rapid combustion of hydrogen gas. This reaction occurs because hydrogen easily reacts with oxygen in the air to form water vapor, releasing energy in the process. The splinter would likely catch fire and burn more vigorously due to the presence of hydrogen gas in the test tube.

As the inverted test tube is inserted into the measuring cylinder containing water, the water will rise up into the test tube due to atmospheric pressure. The level of water inside the test tube will stabilize at a certain height once the pressure inside and outside are balanced. This can be used to measure the volume of the test tube.
The level of water in the test tube will decrease as hydrogen gas is produced. This is because the volume of the gas will displace some of the water in the test tube.
It is captured in an upside down test tube or a gas collecting tube.
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.

The height to which water can rise in a capillary tube is calculated using the equation h = 2γcos(θ)/ρgr, where γ is the surface tension of water, θ is the contact angle, ρ is the density of water, g is the acceleration due to gravity, and r is the radius of the tube. For a tube with a diameter of 0.1 mm, the radius would be 0.05 mm. Water typically has a contact angle close to 0, resulting in a high degree of wetting, allowing it to rise several millimeters in a capillary tube of this size.
Water contains two parts hydrogen and one part oxygen (2 H and 1 O = H2O) Because of this, the amount of hydrogen and oxygen produced during electrolysis of water is in a 2:1 ratio. In electrolysis process, hydrogen goes to one test tube and oxygen goes to another. Because Water contains 2 part hydrogen, the amount of gas collected in one tube is double the amount collected in the other.
