If women are exploited year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion(过时),they are always made use of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is able to stand in front of a wardrobe(衣柜) packed full of clothes and announcing sadly that she has nothing to wear. Changing fashions are nothing more than the intentional(故意的) waste.Many women spend vast （9分）现有A、B、C、D、E五种可溶强电解质，它们在水中可电离产生下列离子（各种离子不重复）。 阳离子 H+、Na+、A13+、Ag+、Ba2+ 阴离子 OH－、Cl－、NO3－ 、CO32 －、SO42－ 已知： ① A、B两溶液呈碱性，C、D、E溶液呈酸性。 常温下，0.1mol/L A溶液的pH小于13， 0.1mol/L C溶液的pH小于1。 ②A溶液与E溶液反应既有气体又有沉淀产生； A溶液与C溶液反应只有气体产生（沉淀包括微溶物，下同）。 ③D溶液与另外四种溶液反应都能产生沉淀。 试回答下列问题： （1）写出D的化学式：                。 （2）将E溶液加热蒸干并灼烧所得产物的名称为：               ； （3）写出A、E溶液反应的离子方程式：                     ； （4）写出B溶液与C溶液恰好完全反应至溶液呈中性的离子方程式：
