the lime water will turn cloudy
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
To do the burning splint test, you light a wooden splint and then blow it out to create an ember. You then place the splint near a gas sample without touching it. If the gas is flammable, it will ignite and produce a flame when the ember from the splint comes into contact with it.
collect gas from reaction with a test tube, then light spint and insert into the gas filled tube. if splint is extinguished immediately, then its CO2. but limewater test is more reliable
A glowing splint will reignite in the presence of oxygen due to the process of combustion. Oxygen feeds the combustion reaction, allowing the splint to continue burning.
the positive test for oxygen is very simple. all that needs to happen is a vile must be filled 1/4 with hydrogen peroxide and a glowing splint must be inserted in t the vile . the splint will reignite after it is inserted int the vile.
a glowing splint in hydrogen gas will make a popping sound. this is because hydrogen is very reactive and when it comes into contact with the oxygen in the air it reacts with it and that is what you hear in the popping sound.

The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
As metal carbonates react with acid, a neutralisation reaction happens. Salt, water, and carbon dioxide are produced. This can be expressed in the following general equation:metal carbonate + acid → salt + water + carbon dioxide To test for carbon dioxide the gas can be bubbled through limewater. Carbon dioxide will dissolve slightly in water to make a weak acid (carbonic acid). Another neutralisation reaction then happens between the limewater (calcium hydroxide) and the carbonic acid. This makes the limewater turn milky, which is the positive result for carbon dioxide.visit : ask-astrologer.blogspot.com for more on this
Oxygen gas will "pop" when a burning splint is inserted into a test tube, due to the rapid combustion reaction that occurs between the oxygen and the flammable material on the splint. This reaction creates a small explosion sound known as a "pop".
Insert a lighted splint into the reaction test tube. If it extinguishes with a "pop" sound, Hydrogen is present. The duller the pop the purer the hydrogen is.---------------------------------------------------------------------------------------------P.S. that's a burning splint.
To do the burning splint test, you light a wooden splint and then blow it out to create an ember. You then place the splint near a gas sample without touching it. If the gas is flammable, it will ignite and produce a flame when the ember from the splint comes into contact with it.
1) Put a burning splint near the mouth of a test tube which you think contains hydrogen. If you hear a pop when you touch it with the splint then there is hydrogen.
hydrogen gas is H2 When H2 reacts with oxygen and fire (energy) It is combustion H2+ 02= 2(H20) Which is water. In that state it is water vapor. A popping noise is also made. That is water vapor racing out. The burning splint tests, basically, is when an individual lights a splint. On lighting this splint, it should be placed near a bottle containing hydrogen gas [ H2 ]. On carrying out this action, the glowing splint may increase in size, regarding the size of the flame, that is. The Hydrogen gas, on the other hand, will make a popping sound. The intensity of the 'pop' will depend on the amount of Hydrogen gas collected in the bottle. Take care to ensure that no Hydrogen gas escapes, or is released from the bottle, until the splint is placed, at least 2 inches away from the opening of the bottle.
A burning wooden splint has a visible flame at its burning end while a glowing wooden splint has glowing ember at its glowing end. Placing a glowing splint in a container with oxygen will cause it to burst into flames and become a burning splint.
You can test for the presence of hydrogen gas using a lit splint test. When a lit splint is exposed to hydrogen gas, it will produce a squeaky pop sound, indicating the presence of the gas. This test is based on the highly flammable nature of hydrogen gas.
