stoichiometric chemistry

Stoichiometric Defects - If imperfections in the crystal are such that the ratio between the anions and cations remain same as represented by the molecular formula, the defect is called a stoichiometric defect. There are three types of stoichiometric defects: Schottky ..

If imperfections in the crystal are such that the ratio between the anions and cations remain same as represented by the molecular formula, the defect is called a stoichiometric defect. There are three types of stoichiometric defects: Schottky defect Frenkel defect Interstitial ..

According to Avagadro the smallest particle of an element, which may or may not have independent existence, is called an atom, while the smallest particle of a substance, which is capable of independent existence, is called a molecule. Molecules are classified as homoatomic and heteroatomic. Homoat..

If an imperfection causes the ratio of cations to anions to become different from that indicated by the ideal chemical formula, the defect is called non-stoichiometric..

If an imperfection causes the ratio of cations to anions to become different from that indicated by the ideal chemical formula, the defect is called non-stoichiometric. There are three types: Metal excess Metal deficiency Impurity defect..

The electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate in regular,continuous..

Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solution. Most common ways of expressing concentration of any solute in a solution a..

The molar volume [22.4L at STP] plays a vital role in stoichiometric calculations because it is the link between volume and mass in reactions involving gase..

The defect, which arises due to the irregularity in the arrangement of atoms or ions are called point defects. Point defects are of three types: Stoichiometric defects Non-stoichiometric defects Impurity defect..

When we add a solution of NaOH to the solution of HCl, the pH progressively increases. This is because OH - ions from the base will react with H + ions of the acid to form water. This decreases the concentration of H + ions and therefore pH increases. The pH of the solution increases only sli..
