How many different types of $OBO$ angles are there in sodium peroxoborate ?
$N{a_2}{B_4}{O_7}.10{H_2}O\xrightarrow{{Heat}}X + NaB{O_2} + {H_2}O,X + C{r_2}{O_3}\xrightarrow{{Heat}}\mathop Y\limits_{\left( {Green\,coloured} \right)} $ $X$ and $Y$ are
$AlF_3$ is soluble in $HF$ only in presence of $KF.$ It is due to the formation of
Hydrated $AlC{l_3}$ is used as
When $BCl_3$, is treated with water, it hydrolyses and forms $[B(OH)_4]^-$ only whereas $AlCl_3$ in acidified aqueous solution forms $[Al(H_2O)_6]^{3+}$ ion. Explain what is the hybridizations of boron and aluminum in these species?
