# What is the Ksp of Al(OH)3?

This site
Aluminum hydroxide $\ce{Al(OH)_3}$ >> $1.3×10^{–33}$

and

This site
Aluminum hydroxide $\ce{Al(OH)_3}$ >> $3×10^{–34}$

which is one order of magnitude different.

What can be the reason for this variation? Experimental conditions? Where can I get accurate or reliable results/data of $K_{\mathrm{sp}}$ in general?

• @Martin-マーチン Done. I can just add their values. – Dexter May 13 '15 at 11:08

• Umm..... $3*10^{-34}$ is the answer as it appears most times. – Dexter May 26 '15 at 16:42
