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
Weak Acid pH Calculator This is a calculator to find values of a weak acid dissociation reaction. All concentrations are measured in M (mol/liter). Values are found using the equilibrium constant formula, where the product of the concentration of products to the power of their coefficients is ...

Step 5: Calculate KaCalculating Ka:Ka=10−4.2Using a calculator:Ka≈6.31×10−5 Step 6: ConclusionThe dissociation constant Ka of benzoic acid is approximately 6.31×10−5. Final AnswerThe dissociation constant of the acid is 6.31×10−5 (Option A). --- Show More ...
Answer:The reason for the above mentioned changes is the common-ion effect. When CH3COONa is added to the weak acid CH3COOH, CH3COONa dissociates completely. While CH3COOH being a weak acid does not dissociate completely. The dissociation of CH3COOH gets even more hindered due to the generation ...
[29,30]. It is quite apparent from the inhibition data that the activity of CDK6 decreases with increasing concentration of EA and shows a concentration-dependent relationship. IC50was calculated with an AAT Bioquest calculator [31] (Figure S3C) and was found to be 3.053 µM. These ...
