Yes, by quite good approximation with this formula:
Ka = [H+]2/ [Acid]
So, by knowing the dissolved weak acid concentration [in mol/L] and by measuring the pH, which is recalulated into [H+] value, this can be solved.
[H+] = 10-pH
It is mostly valid for pH ranges below 6
The weak acids and bases chart provides information about the names, formulas, dissociation constants, and pH ranges of various weak acids and bases. It helps in understanding their properties and behavior in solution.
An acid dissociation constant (Ka) measures the strength of an acid in a solution. The most commonly used form of this consant is the logarithmic constant, pKa, which is equal to -log10Ka. A weak acid usually has a pKa value between -2 and 12 in water, meanwhile a strong acids have a pKa value less than -2.
To determine the pH of polyprotic acids, one can use the stepwise dissociation constants of each acidic proton and calculate the concentrations of the acid and its conjugate base at each stage of dissociation. By considering the equilibrium concentrations of the acid and its conjugate base, one can then use the Henderson-Hasselbalch equation to calculate the pH of the solution.
The strength of an acid can be determined by its ability to donate hydrogen ions in a solution. Strong acids completely dissociate in water, while weak acids only partially dissociate. This can be measured using pH levels or acid dissociation constants.
Ka and Kb are equilibrium constants for the dissociation of acids and bases, respectively. A higher value of Ka or Kb indicates a stronger acid or base, respectively. The relationship between Ka and Kb can be described by the equation Kw = Ka x Kb, where Kw is the autoionization constant of water.

Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.
yes

The Ka value of a weak acid is inversely related to its acid strength. A higher Ka value indicates a stronger acid, while a lower Ka value indicates a weaker acid. Acid strength is determined by the extent of dissociation of the acid in solution, with stronger acids having higher dissociation constants (Ka values).
Yes. Unless you are talking about dissociation of acids.
Monoprotic acids are acids that can donate only one proton (H⁺) per molecule during dissociation, such as hydrochloric acid (HCl). In contrast, polyprotic acids can donate more than one proton; they can release two or more protons in a stepwise manner, such as sulfuric acid (H₂SO₄), which donates two protons. The dissociation of polyprotic acids typically occurs in multiple stages, each with its own acid dissociation constant (Ka).
