some of the acid has dissociated APEX
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.
