types of buffer solutions

Buffers - Certain solutions, such as that of ammonium acetate, have a tendency to resist any change in its hydronium ion concentration or pH, whenever a small amount of a strong acid or a strong base is added to it. This property of a solution is known as buffer..

The effectiveness of any buffer is described in terms of its buffer capacity. It is defined as, 'the number of equivalents of a strong acid (or a strong base) required to change the pH of one litre of a buffer solution by one unit, keeping the total amount o..

A buffer solution containing a large amounts of a weak acid, and its salt with a strong base, is termed as an acid buffer. Such buffer solutions have pH on the acidic side i.e., pH is less than 7 at 298 K. The pH of an acid buffer is give..

The buffering action of buffer solutions can be explained in terms of the Bronsted-Lowry concept of acids and bases as follow..

An acid buffer contains relatively large amounts of a weak acid (HA) and its salt with a strong base (say NaA). The buffer solution thus contains large concentration of HA and A - (due to the dissociation of the salt), apart from H 3 O + and OH - . An addition of sm..

A solution can be solid, liquid or a gas depending upon the physical state. The various types of solutions are: Solute Solvent Types of solutions Examples Solid Solid Solid in Solid Alloys Liquid Solid Liquid in S..

Is Matter Around us Pure - Types of Solutions Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gas. For example: common salt in water (liquid solution), air (g..
