positive health solutions

These types of solutions where D H of mixing is >0 and D V of mixing >0 are found to exhibit positive deviation from Raoult's law. Here solute-solute interactions and solvent-solvent interactions are greater than solute - solvent interaction..

Solutions With Positive Deviation - These types of solutions where D H of mixing is >0 and D V of mixing >0 are found to exhibit positive deviation from Raoult's law. Here solute-solute interactions and solvent-solvent interactions are greater..

Li + ion has small size and has maximum tendency to distort the electron cloud of the anion by withdrawing the electrons from the negative ion towards itself. This tendency to distort the electron cloud of the negative ion by the positive ion is known as polarization. It causes the char..

The electronic configurations of aluminium (At. no. 13) and fluorine (At. no. 9) atoms are 2,8,3 and 2,7 respectively. Aluminium has 3 electrons in excess of its nearest noble gas (neon) configuration. Fluorine is one electron short of its nearest noble gas (neon) configuration. Therefore, one ato..

From the charges on the ions, the number of positive and negative ions in the compound can be found out. This gives the empirical formula (E.F.) Lewis formula:..

In 1884 a Danish physician Christian Gram devised a technique of differential staining for bacterial cells, using two simple stains. The procedure involves staining bacteria initially with a weak alkaline solution of gentian (crystalline) violet. All bacterial cells stain blue with this d..

The absorption and conduction of mineral nutrients is called translocation. Soil serves as a main source of mineral salts in which clay crystals with a central nucleus is called micelle. The micelles are negatively charged. To maintain the balance, they hold positively charged ions on the..

For minimum deviation position, or Similarly, or or ..

In general, most of the solutions deviate from ideal behavior. There are two types of deviations, positive deviation and negative deviations. Such solutions are called non ideal solutions..

Let us suppose a small amount of a non-volatile solute (sugar) is dissolved in a solvent (water). When evaporation of this solution takes place, only water evaporates as the other component (i.e., sugar) is non-volatile. The vapor pressure of the solution is found to ..
