Download Solution PDF0.2 M NaOH দ্রবণে Al(OH)3 এর মোলার দ্রাব্যতা কত? প্রদত্ত, Al(OH)3 এর দ্রাব্যতা গুণফল = 2.4 x 10-24:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFধারণা:
ধরা যাক Al(OH)3 এর দ্রাব্যতা হল s
Al(OH)3 ⇌ Al3+ + 3OH-
s 3s
NaOH ⇌ Na+ + OH-
0.2 M 0.2M
গণনা:
[Al3+] = s এবং [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 May 23, 2025
