Download Solution PDF0.2 M NaOH विलयन में Al(OH)₃ की मोलर विलेयता क्या है? दिया गया है कि, Al(OH)₃ का विलेयता गुणांक = 2.4 x 10⁻²⁴
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
मान लीजिये Al(OH)₃ की विलेयता है
Al(OH)₃ ⇌ Al³⁺ + 3OH⁻
s 3s
NaOH ⇌ Na⁺ + OH⁻
0.2 M 0.2M
गणना:
[Al³⁺] = s और [OH⁻] = 3s + 0.2 ≈ 0.2
ksp = 2.4 x 10⁻²⁴ = [Al³⁺] [OH⁻]³
2.4 x 10⁻²⁴ = s(0.2)³
\(s = \frac{{2.4 \times {{10}^{ - 24}}{\rm{\;}}}}{{8 \times {{10}^3}{\rm{\;}}}} = 3 \times {10^{ - 22}}\;{\rm{mol}}/L\)Last updated on Jul 21, 2025
