Applications of Buffers

The use of Buffers is an important part of many industrial processes for examples are electroplating and the manufacture of leather, photographic material's and dyes

In bacteriological research, culture media are generally buffered to maintain the pH required for the growth of the bacteria being studied

Buffers are used extensively in analytical chemistry and are used to calibrate pH. Human blood is buffered to pH of 7.4 by means of bicarbonate, phosphate and complex proteins system.For human body to function normally, the blood pH must stay within the range 7.35 to 7.45.if the pH of a person,s blood drop below 7.35, one is said to have acidosis or low blood pH .it can cause disorientation and coma. An anxiety attack or hysteria can cause a person to breath rapidly. Under these conditions, the blood pH may rise to 7.6 or 7.7 within minutes, resulting in alkalosis which causes vomiting common buffers with their pH values are

Buffer. pH

NH⁺₄ NH_3. 9

CH₃COOH, CH₃COO^{-. 3.5}
