Chemistry Concepts – Mole concept, Eudiometry, POAC, Limiting is given, then the question is based on the concept of limiting reagent. Eudiometry: Eudiometry. means gas analysis. It means in this type of numericals either you have to find out vol. of GAS From the data given in question or you. Such a tube is known as Eudiometer tube and hence the name Eudiometry General Assumptions: In all problems, it is assumed that the sparking occurs at.

In all problems, it is assumed that the sparking occurs at room temperature.

Gas Eudiometry – Quantum Study

qjestions From the data thus collected a number of useful conclusions regarding reactions amongst gases can be drawn. Thus ammonia will diffuse 1.

For metals in hydrides, oxides and chlorids, eq. Xpress Buy Xpress Buy.


In all problems, it is assumed that the sparking occurs at room temperature. Studying in Grade 6th to 12th? The limiting reactant can also be ascertained by knowing the initial number of equivalents of each reactant. Gaseous reactions for investigation purposes are studied in a closed graduated tube open at one end and the other closed end of which is provided with platinum terminals for the passage of electricity through the mixture of gases.


Effusion is the process by which a gas escapes from one chamber of a vessel through a small opening or an orifice. Also browse for eudiometty study materials on Chemistry here.

During Gas analysis, the Eudiometer tube filled with mercury is inverted over a trough containing mercury. Whenever balanced chemical equation is given, mole method is very useful. All calculations are to be carried out with the amount of the limiting reactant only. One equivalent of any substance is the amount of that substance that combines with 1 g H or displaces 1 g H.

A known volume of the gas or euiometry mixture to be studied is next introduced, quuestions displaces an equivalent amount of mercury.

Law of chemical equivalence: This principle states that the moles of atoms of an element are conserved throughout the reaction. The balanced equation for combustion. Equivalent weights of some elements: Leave a Reply Cancel reply You must be logged in to post a comment. The volumes of carbon dioxide, water vapour or other gaseous products of combustion are next queetions by absorbing them in suitable reagents.

Which of the two gases ammonia and hydrogen chloride will eudiommetry faster and by what factor? Register yourself for the free demo class from askiitians.

Will the same be true if any hydrocarbon is completely combusted? The points P, Q and R are the centres of the three triangles. Next a known excess of oxygen is introduced and the electric spark is passed, whereby the combustible material gets oxidised. Diffusion in the ability of a gas to euriometry and occupy the whole available volume irrespective of other gases present in the container.

For metals in hydrides, oxides and chlorids. For example, the volume of CO 2 is determined by absorption in KOH solution and that of excess of oxygen in an alkaline solution of pyrogallol.


A known volume of the gas or gaseous mixture to be studied is next introduced, which displaces an equivalent amount of mercury.

The excess of oxygen left after the combustion is also determined by difference if other gases formed during combustion have already been determined. Our IITian faculty will contact you in 1 working day.

MOB20 View Course list. Plane to See P is the midpoint of an edge of a cube and Q divides another edge in the ratio 1 to 4.

Eudiometry :

Are there any extreme cases which give rise to very large changes in volume? Advantages of Mole Method over other Methods: DearPreparing for entrance exams? Similarly, for H 2 C 2 O 4. Water vapour produced during the reaction can be determined by noting contraction in volume caused due to cooling, as by cooling the steam formed during combustion forms liquid water which occupies a negligible volume as compared to the volumes of the gases considered.

The balanced equation for combustion. A gaseous hydrocarbon requires 6 times its own volume of O 2 for complete oxidation and produces 4 times its volume of CO 2. What can you say about triangle PQR? H 2 O 2 oxygen?
