【简答题】
矿泉水一般是由岩石风化后被地下水溶解其中的一部分生成的。此处所指的风化作用是指矿物与CO 2 作用的过程。例如，钾长石(KAlSi 3 O 8 )风化生成高岭土[Al 2 Si 2 O 5 (OH) 4 ]，此反应的离子方程式为2KAlSi 3 O 8 ＋2H 2 CO 3 ＋5H 2 O=2K ＋ ＋2HCO＋4H 2 SiO 3 ＋Al 2 Si 2 O 5 (OH) 4 。 (1)将上述复杂硅酸盐改写成氧化物形式： ①KAlSi 3 O 8 _____________________________________________________。 ②Al 2 Si 2 O 5 (OH) 4 ________________________________________________。 (2)这个反应能够发生的原因是_________________________________________。
