What is the pKa of CH3CH2SH?
The half equivalence point represents the point at which exactly half of the acid in the buffer solution has reacted with the titrant. The half equivalence point is relatively easy to determine because at the half equivalence point, the pKa of the acid is equal to the pH of the solution.
The pH at the midpoint, the point halfway on the titration curve to the equivalence point, is equal to the pKa of the weak acid or the pKb of the weak base.
Ka is acid dissociation constant and represents the strength of the acid. pKa is the -log of Ka, having a smaller comparable values for analysis. They have an inverse relationship. Larger the Ka, smaller the pKa and stronger the acid.
What Does the “p” Mean? Whenever you see a “p” in front of a value, like pH, pKa, and pKb, it means you’re dealing with a -log of the value following the “p”. For example, pKa is the -log of Ka. Because of the way the log function works, a smaller pKa means a larger Ka.
