Ka vs [H+] at Equilibrium
सूत्र
## How to Calculate Ka ### Formula **Ka = [H+][A-] / [HA]** For the equilibrium: HA <-> H+ + A-
हल किया गया उदाहरण
At equilibrium: [H+]=0.004, [A-]=0.004, [HA]=0.096 M.
- 01Ka = (0.004 × 0.004) / 0.096
- 02Ka = 0.000016 / 0.096
- 03Ka = 1.67 × 10^-4
- 04pKa = -log10(1.67 × 10^-4) = 3.78
अक्सर पूछे जाने वाले प्रश्न
What is Ka?
The acid dissociation constant measures the strength of a weak acid. Larger Ka means stronger acid (more dissociation).
What is pKa?
pKa = -log10(Ka). Lower pKa means stronger acid. It is more convenient for comparing acids.
Do strong acids have Ka values?
Strong acids fully dissociate, so their Ka is very large (effectively infinite). Ka is mainly used for weak acids.
