Test Preparation

In Biochemistry, pH is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the base 10 logarithm of the activity of the hydrogen ion. At 25 °C, solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic.

Introduction to pH Concept

Acid and Base

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pHchanges very little when a small amount of strong acid or base is added to it.

Buffer and its Principle

In chemistry and biochemistry, the Henderson–Hasselbalch equation can be used to estimate the pH of a buffer solution containing given concentrations of an acid and its conjugate base. The numerical value of the acid dissociation constant of the acid must also be known.

Handerson-Hasselbalch Equation

Handerson-Hasselbalch Problems

A variety of buffering systems exist in the bodythat helps maintain the pH of the blood and other fluids within a narrow range—between pH 7.35 and 7.45. A buffer is a substance that prevents a radical change in fluid pH by absorbing excess hydrogen or hydroxyl ions.

Biological Buffer System

he buffer systems functioning in blood plasma include plasma proteins, phosphate, and bicarbonateand carbonic acid buffers. The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range.
