Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in nature...

Ammonia molecule has a strong tendency to donate its lone pair of electrons of nitrogen to other molecules. Thus, it acts like a strong Lewis base. In aqueous solutions, NH 3 ionizes in accordance with the reaction...

During a redox reaction, the total increase in oxidation number must be equal to total decrease in oxidation number. This is the basic principle for balancing chemical equations. In addition, the number of atoms of each kind on one side of the equation must be equal to the number of atom..

2 and MO type oxides. Their chemistry is characterized by (+2) oxidation state. In general, the heavier p-block elements favor low oxidation states. The most important element of group 15 is phosphorus. It exists in white, red and black allotropic forms. It forms ..

While all oxides are basic in nature, BeO is amphoteric reacting with acids as well as alkalies. The basic character of oxides decreases from Be to Ba because of decrease in polarizing power with increase in ionic size. BeO MgO CaO, SrO, BaO Amphoteric Weakly basic ..

Dalton's Atomic Theory - John Dalton provided a simple theory of matter to provide theoretical justification to the laws of chemical combinations in 1805. The basic postulates of the theory are: All substances are made up of tiny, indivisible particles called atoms. Atoms of the same ..

These react with oxygen at room temperature to form respective oxides. These oxides are basic in nature and react with water to give the corresponding alkali. ..
