The pKa value is the negative base -10 logarithm of the acid dissociation constant (Ka) of a solution. The quantitative behavior of acids and bases in solution can be understood only if their pKa values are known.
In words, the pOH is the negative logarithm of the hydroxide ion concentration. Example #1: The [OH¯] in a solution is measured to be 0.0010 M. What is the pOH? Solution: 1) Plug the [OH¯] into the pOH definition: pOH = −log 0.0010. 2) An alternate way to write this is: pOH = −log 10¯ 3. 3) Since the log of 10¯ 3 is -3, we have: pOH = − (−3)
3 Αυγ 2024 · The equilibrium equation yields the following formula for pH: pH = -log 10 [H + ] [H + ] = 10 -pH In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value.
Logarithms are the mathematical function that is used to represent the number (y) to which a base integer (a) is raised in order to get the number x: x = ay; where y = loga(x). Most of you are familiar with the standard base-10 logarithm: y = log10(x); where x = 10y.
Using this calculator, you can find the negative logarithm of any number with any chosen base. For details on logarithms and how to find the negative log of a number, read the description given below.
14 Ιουν 2024 · pH is the negative of the base-ten logarithm of the concentration of H + or H 3 O + expressed in moles/liters. pH scale has values ranging from 0 to 14. A solution is classified as a neutral, acidic, or basic solution on the basis of the given criteria:
