Aluminium chloride exists as dimer, $A{l_2}C{l_6}$ in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives
${[Al{(OH)_6}]^{3 - }} + 3HCl$
${[Al{({H_2}O)_6}]^{3 + }} + 3HCl$
$A{l^{3 + }} + 3C{l^ - }$
$A{l_2}{O_3} + 6HCl$
$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
