2. pKa, also known as the acidity coefficient, is a measure of the acid's dissociation constant, which is crucial in fields such as chemistry and biochemistry.3. Different acids have different acidity coefficients, leading to the use of pKa to represent these values, which are the...
Ka chemistry - An acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution. An acid dissociation constant, Ka is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a c
Converting to pKa Ka values can be very large or very small. For example, the Ka value for hydrochloric acid (HCl) is around 107, while the Ka value for ascorbic acid (vitamin C) is 1.6 X 10-12. Working with such numbers is inconvenient, so to makes things easier, chemists have defi...
pKa: Ka is the equilibrium constant for the dissociation of an acid. We often express it as the negative log, or pKa. A lower pKa corresponds with a higher dissociation, and as a result, typically means higher acidity (it is more likely to give up its protons). ...

pH = pKa2 + log([Ma(2-)]/[HMa-]) rearranging: pKa2 = pH + log([HMa-]/[Ma(2-)]) using calculator: pKa2 = 6.03 + log(0.25/0.5) = 5.73 To not look further pKa1/2 for malonic acid taken from BATE database are 2.847 and 5.696. That's almost perfect fit....
