Answer :
The Kb of CH₃COâ‚‚- is approximately 5.56 × 10⻹â°, closest to option A: 5.88 × 10⻹¹.
To calculate Kb, we need to use the relationship between Ka and Kb, which is given by the equation: Ka × Kb = Kw, where Kw = 1.0 × 10⻹â´.
For acetic acid (CH₃COâ‚‚H), the Ka is given as 1.8 × 10â»âµ. Using the relationship between Ka and Kb:
(1.8 × 10â»âµ)Kb = 1.0 × 10⻹â´
Solving for Kb, we get:
Kb = 1.0 × 10⻹ⴠ/ 1.8 × 10â»âµ = 5.56 × 10⻹â°.
