introduction to solutions

Introduction - A Solution is a homogeneous mixture of two or more chemically non-reacting substances called components. The composition of the components can be varied with in certain limits. When two components are present - Binary solution. When three components are ..

Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced in ..

The phenomenon of electrolysis is an important chemical effect of electric current. In a metallic conductor, the electric current is due to the drifting of free electrons, there is no chemical or physical change, only the generation of heat. However, in ionic solutions (electrolytes), the..

The plants upon which we depend for the food we eat, and for the oxygen we breathe, depend in turn upon the soil. A good soil supplies the plants with the mineral elements they use. Vigorous, highly productive plants can be grown in solutions of fertilizer minerals in the absence of..

The different kinds of micromolecules and macromolecules that we have studied so far occur in the cell dissolved in solution or as suspensions in a colloidal state. Alternatively, they may be assembled into subcellular components like cell membrane, cytoplasm and cell organelles. In..

The nitrogenous waste materials produced in the animal body due to metabolic reactions are of no use to the cell. These waste materials if allowed to accumulate in the body, may become toxic. Therefore, they must be removed from the body. The process of elimination of metabolic waster products from..

. Litmus, a purple dye extracted from the lichen plant, is commonly used as an indicator in laboratories. Acids change the colour of litmus solution to red, and bases change the colour of litmus solution to blue. Turmeric is another common household indicator. A stain of turmeri..
