ionic equilibrium in indicators

Ionic Equilibrium - This type of equilibrium is observed in substances that undergo ionization easily, or in polar substances in which ionization can be induced. Ionic and polar substances are more easily soluble in polar solvents because of the ease of ioniz..

Introduction - 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 solution. The..

Universal Indicators - A mixture of several indicators with a wide range of pH is an universal indicator. These are obtained by mixing certain indicators that behave like a single indicator. The changes in colour may occur over a considerable portio..

Acid Base Titrations and Indicators - Titration is an operation for the measurement of quantities of substances in solution by the method of 'volume analysis'. This process involves adding a solution of the reagent of known concentration (standard solution), taken in a burette (called 'ti..

Ionic Equations - Suppose we dissolve silver nitrate, an ionic solid in water, the ions in the crystal lattice are released and once in solution, move freely in hydrated form. The situation is represented by the equatio..

where, K I n d is known as indicator constant. Writing the above equation in logarithmic form Thus the colour of the indicator, which is determined by the ratio Similarly, for a weak organic base indicator, In O..

The magnitude of equilibrium constant K is a measure of the extent to which the reversible reaction has proceeded at equilibrium. The larger the value of the equilibrium constant, the greater is the extent to which the forward reaction takes place and therefore the gre..
