Colligative properties
In colloidal systems the number of colloidal particles per litre of the sol is relatively much smaller than solute particles in a true solution. Colloidal particles are aggregates of simple molecules and colligative properties such elevation in ..
Colligative Properties
Certain properties of solutions depend only on the number of particles of the solute (molecule or ions) present in definite volume of the solution and do not depend on the nature of solute. Such properties are called colligative ..
Colligative Properties - Depression in Freezing Point
Colligative Properties - Depression in Freezing Point - Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of th..

In other words, solid and liquid forms of th..Osmotic Pressure as a Colligative Property
For a given solvent the osmotic pressure depends only upon the molar concentration of solute but does not depend on its nature. The following relation relates osmotic pressure to number of moles of solute: p V=nRT Van't Hoff 's solution equation ( p = Osmotic pressure)..

Colligative Properties - Osmotic Pressure
Colligative Properties - Osmotic Pressure - The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentr..

Ammonia (240 K) has a higher boiling point than phosphine (190 K) and then the boiling point increases down the group because of increase in size. In PH 3 and other hydrides, the intermolecular forces are Van der Waals' forces. These van der Waals' forc..

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Consequently, the metallic bonds in these metals are not very strong and ..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Incredible help, saved me from failing a test. Thank you so much. This tutoring is amazing! Explains things well, KUDOS - pam
