A Ka value of approximately 1 indicates that the equilibrium of the acid dissociation reaction is about balanced between the reactants and products. This suggests that the acid is neither a strong acid nor a weak acid but has a moderate tendency to donate protons. At this value, significant amounts of both the undissociated acid and the dissociated ions are present in the solution. Consequently, the acid has a notable capacity to ionize, reflecting a relatively sizable equilibrium constant.
A Ka value of approximately 1 indicates that the acid is of moderate strength, suggesting that the equilibrium between the acid and its dissociated ions is relatively balanced. This means that significant amounts of both the undissociated acid and its ions are present in solution. In such cases, neither the forward nor the reverse reaction is strongly favored, indicating a dynamic equilibrium where both forms coexist in appreciable quantities.
The K value, or acid dissociation constant (Ka), indicates the strength of an acid in solution. A smaller Ka value corresponds to a weaker acid, as it signifies a lower degree of dissociation in water. Therefore, the weakest acid would have the smallest Ka value, approaching zero, indicating that it does not ionize significantly in solution.

The Ka value of nitric acid (HNO3) is approximately 25 × 10^6.
The Ka value for hydrobromic acid (HBr) is approximately 9.0 x 10^-10.
According to CRC reference data, the pKa of sulfamic acid is 1.05, giving a Ka of 11.2. This is a strong acid.
It would mean that at equilibrium approximately half of the acid had dissociated. Normally strong acids are defined as having a Ka >1 and weak acids Ka <1. At exactly 1 you would have something right on the border between the two.
Ka= [h+][HCO3-]/[H2CO3]
The pKa value is the negative logarithm of the acid dissociation constant (Ka). To find Ka from pKa, you can use the formula ( Ka = 10^{-\text{pKa}} ). For a pKa of 10.26, the calculation would be ( Ka = 10^{-10.26} ), which is approximately ( 5.5 \times 10^{-11} ). Thus, the Ka corresponding to a pKa of 10.26 is about ( 5.5 \times 10^{-11} ).
The Ka value of ammonium (NH4+) is 5.6 x 10^-10.
The accepted Ka value for sodium hydroxide (NaOH) is not applicable, as NaOH is a strong base and completely dissociates in water. Instead, the equilibrium constant Kb (base dissociation constant) is typically used for strong bases. The Kb value for NaOH is approximately 1 x 10^-15.
ka= 1.62 x 10^-12
The Ka for acetic acid (CH3COOH) is approximately 1.8 x 10^-5. This value represents the acid dissociation constant for acetic acid, indicating its strength as a weak acid. An acid with a higher Ka value will dissociate more readily in solution.
