Bài 9 ...........

Em tham khảo nha:

\(\begin{array}{l}
BT9:\\
C{H_3}COOH \rightleftarrows C{H_3}CO{O^ - } + {H^ + }\\
AlC{l_3} \to A{l^{3 + }} + 3C{l^ - }\\
A{l_2}{(S{O_4})_3} \to 2A{l^{3 + }} + 3S{O_4}^{2 - }\\
AgN{O_3} \to A{g^ + } + N{O_3}^ - \\
Ba{(OH)_2} \to B{a^{2 + }} + 2O{H^ - }\\
 \Rightarrow C{H_3}COOH < AgN{O_3} < Ba{(OH)_2} < AlC{l_3} < A{l_2}{(S{O_4})_3}
\end{array}\)
