EUDIOMETRY QUESTIONS PDF

Diffusion in the ability of a gas to spread and occupy the whole available volume irrespective of other gases present in the container. Effusion is the process by which a gas escapes from one chamber of a vessel through a small opening or an orifice. The law states that under similar conditions of temperature and pressure, the rates of diffusion of gases are inversely proportional to the square roots of their densities. The rate of diffusion r of a gas at constant temperature is directly preoperational to its pressure.

Is there some information missing in the question regarding solute A? I assumed it as the final solution after the reaction, but still don't know how to proceed.

Answer is Mathew Mahindaratne I'm not sure how this question was intended. You could get the vapour pressure of water at the given temperature from published data pure water: A complicating factor is that CO2 is soluble in water - maybe you are supposed to ignore that.

If the non-volatile solute makes the solution acidic, not much CO2 will dissolve, but if it is basic, a lot will dissolve. Are you including water in that, or is that just CO2?

Gas Eudiometry

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. Such a tube is known as Eudiometer tube and hence the name Eudiometry also used for Gas analysis. During Gas analysis, the Eudiometer tube filled with mercury is inverted over a trough containing mercury. A known volume of the gas or gaseous mixture to be studied is next introduced, which displaces an equivalent amount of mercury. Next a known excess of oxygen is introduced and the electric spark is passed, whereby the combustible material gets oxidised. The volumes of carbon dioxide, water vapour or other gaseous products of combustion are next determined by absorbing them in suitable reagents. 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.
