WitrynaIn Biotechnology, we can apply the use of logarithms to find pH and hydrogen ion concentration [H+]. We can do so using either of these two formulas: pH = -log [H+] and [H+] = 10-pH Remember when we covered that relationship between exponents and logarithms where a x = y can be re-expressed as log a y = x? WitrynaA logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2. Hence, we can conclude that, Logb x = n or bn = x. Where b is the base of the logarithmic function. This can be read as “Logarithm of x to the base b is equal to n”. knife river trainingWitryna1 lut 2024 · The pH scale is a scale containing values from 0 to 14, where 0 indicates that the solution is very acidic, and 14 indicates it is very alkaline.

"Witryna28 lut 2024 · logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8. In the same fashion, since 102 = 100, then 2 = log10 100. … " - Logarithm ph
