liquid in the delivery tube is depressed below the level of the solution in the test-tube is a measure of the vapour-pressure. The observed depression must be corrected for capiL-larity. The test-tube is then removed and weighed in order to ascertain the mass of the solution, and if ...
If two liquid A and B from minimim bonding azertrope at some specific composition then A-B interactions are weaker than those of A-A and B-B it is due to the fact that in case of positive deviation, get minimum boilling azeotropes whereas in case of naga
Vapour Pressure of Liquid Solutions: A solution is formed when a solute is dissolved in a solvent. The solvent is generally a liquid. The solute can be a solid, liquid or gas. Additionally, a solution may contain one or more volatile components. Generally, the solvent which is in a ...
6gof urea ( molecular weight=60)was dissolved in9.9moles of water. If the vapour pressure of pure water isP∘, the vapour pressure of solution is: View Solution The vapour pressure of pure benzene at25∘Cis 180 mm Hg. The vapour pressure lowering caused by the addition of 2.5 g of ...

In other words, that the vapour pressure near a very thin film may be less than it can be near a thick one at the same temperature. It is evident that inside or outside a solid box stability must be possible, so that the second alternative is the only solution....

The pulmonary deposition of99mTc-labelled hexamethyl propylene amine oxime, used as a model for propellant soluble drugs, was studied in healthy volunteers using gamma scintigraphy. The radiolabel was delivered using a metered dose inhaler using a low vapour pressure chlorofluorocarbon fill (LVPA, 255...
