People, like your grandparents, use folklore and proverbs to help forecast the weather. They remembered what conditions caused ch以下是我们日常生活中常用的清洗剂，其名称及有效成分如下表：清洗剂的名称洁厕灵“84”消毒液污渍爆炸盐活氧彩漂有效成分盐酸NaClO过碳酸钠过氧化氢（1）“洁厕灵”可以清除铁锈（主要成分是氧化铁），写出该反应的化学方程式________。（2）“洁厕灵”与“84”消毒液混合会发生如下反应：2HCl+NaClO═X+H2O+Cl2↑，对人体造成伤害。下列说法不正确的是___________（填序号）。 ①物质X由离子构成 ②NaClO中氯元素的化合价为-1 ③“洁厕灵”能用于清除水垢（主要成分是碳酸钙和氢氧化镁） ④对人体造成伤害的物质是氯气（3）“污渍爆炸盐”溶于水，生成Na2CO3和H2O2，再加入足量的“洁厕灵”，产生能使澄清石灰水变浑浊的气体，写出产生该气体的化学方程式_______________________。（4）“活氧彩漂”可用于漂洗衣物、杀菌消毒等，原因是其有效成分过氧化氢分子中含有“过氧基”（—O—O—）。据此推测，下列物质中可用作杀菌消毒剂的是________（填序号）。
