Concentrations in biochemical systems are often very dilute. Consequently, scientific notation and logarithms are often used to express concentrations. In scientific notation, numbers are expressed as coefficient x 10" To convert a number to scientific notation, proceed as follows: 1. Move the decimal place so that there is one digit in front of the decimal. 2. Account for the moved decimal in the value of x. If the decimal moved to the right, x is negative; if it moved to the left, x is positive. A logarithm is basically an exponent. Unless otherwise indicated, a logarithm is the a of 10". The numbers after the decimal point are significant; the number before the decimal just identify the location of the decimal point for the number. Notice that it is easy to estimate a logarithm from scientific notation; it's the exponent! Logarithms are commonly used to express the concentration of H. The pH is defined as pH= log (In), where the base number is 2.303. The same general rules as logs…
