In 3H2SO4 + 2AlCl3 - Al2(SO4)3 + 6HCl ...

In 3H2SO4 + 2AlCl3 -> Al2(SO4)3 + 6HCl, why AL reacts with SO4 ions rather than remaining as ALCL3??? 其實係點樣分有冇reaction 發生?
有咩方法何以predict products from reactants given?

唔係Al 揀 SO4
而係 H+ 揀 Cl-

你可以跟番Ionising power 黎predit

呢條反應係睇H2SO4的濃度決定....
如果H2SO4的濃度高，就可以成立...
因為沸點高的酸是可以與沸點低的酸根離子鹽反應，生成沸點低的酸
