∙ 13y agoThis works as long as the gas is not significantly soluble in water. If it is, use another liquid in which the gas is not soluble.
Do the reaction in a flask which is sealed except for a tube coming out of the flask. Put the other end of the tube in a graduated cylinder. It is helpful to have some idea of about how much gas you expect from the reaction, as you need to choose a graduated cylinder that is approximately the right size. Fill the graduated cylinder with water. Take a large tub or bowl of water, and put the graduated cylinder (with the hose in it) upside down in the water bowl. Hold it in place, and begin the reaction. The gas will displace the water, and you can measure the volume.
For more detailed instructions with a diagram, see the Web Links.
You could also use a gas syringe to collect the gas

Why does breaking the object in many pieces affect the rate of chemical weathering?
Grinding or powdering an object increases the surface volume available for chemical interaction. More the reagent is individualized more effecient is the reaction with it's environment.
What are substances that change when the become involved in chemical reaction?
Rust is formed by the chemical reaction of oxygen to iron. This process is called oxidation and occurs when ever iron (or some other materials) are exposed to oxygen. The result makes a new substance: rust.
What does a flask measure?
Volume.
What volume of hydrogen chloride is produced by the reaction of 40 cm3 of chlorine with hydrogen?
Assuming that hydrogen, chlorine, and hydrogen chloride are all ideal gases and that the temperature and pressure are kept constant, the volume of gas depends only on the number of molecules of gas present. Also, at standard temperature and pressure, hydrogen and chlorine occur as diatomic molecules, and hydrogen chloride also occurs as diatomic molecules. The equation for the reaction is Cl2 + H2 -> 2 HCl. Therefore, the number of molecules of gas is the same before and after the reaction if both gases are present in the initial mixture that has a volume of 40 cm3. In that instance, the volume is the same before and after the reaction. However, the question seems to imply that hydrogen is supplied from an outside source. In that instance, there will be twice as many molecules after the reaction as before, so that the final volume will be 80 cm3.
A measure of how tightly matter is packed?
volume
What volume of hydrogen gas is produced at stp as sulfuric acid reacts with 120 g of metallic calcium in a single replacement reaction?
The chemical reaction is:Ca + H2SO4 = CaSO4 + H2The volume of released hydrogen is 66,6 L.
Does volume not change when a chemical reaction takes place?
The volume is changed.
Is volume a physical property or chemical?
Volume is a physical property.
Is mass and volume conserved in a chemical change?
No. Mass must be conserved in a chemical changes according to the law of conservation of mass, which holds that the mass of the reactants and the mass of the products of a chemical reaction must be equal. However, there is no similar law about conserving volume and volume can change dramatically if a gas is produced.
What states that volume is neither created nor destroyed in chemical reaction?
As far as I know this is not true- volume can be increased or decreased. What is conserved in a chemical reaction is mass. Matter is not created or destroyed.
How a cylinder is used in science?
Well, that depends on what cylinder you are using. For example, a graduated cylinder is used to measure the volume of a liquid, the measure of a solid by displacement, or for measuring quantities of volumes to be added into a mixture or chemical reaction.
How much mass is given off as gas during a chemical reaction?
The amount of mass given off as gas during a chemical reaction depends on the stoichiometry of the reaction and the molar mass of the gas produced. It can be calculated using the ideal gas law, which relates the pressure, volume, temperature, and number of moles of a gas.
What is an ediometer and how it is used?
A eudiometer is a device used to measure the volume of a gas that changes with a chemical reaction. It is used by placing the open end in water and then measuring the gas change on the side.
Substance with a definite shape and volume?
Items like H2O and CoC2 have a definite chemical composition, and require exact amount of particles to forma reaction. However; particles which are soluble in water do not have a definite chemical reaction.
What is a gas syringe and how is it used?
A gas syringe is basically a device that fills up with a gas that is produced and gives a volume for that gas. Gas from a reaction is forced into the syringe due to pressure and the syringe plunger is forced out (just like how you suck up a liquid with a normal syringe). It can be used to detect the volume of gas produced in a chemical reaction for instance.See the Web Links to the left for more information.
A chemical reaction produces 0.884 mol of H2S gas What volume will that gas occupy at STP?
The volume is 22,1 L.
How would the volume of a gas change if a reaction produced 1 mole of gas from 2 moles of gaseous reactants?
The volume is 50 %.
