正常雨水偏酸性,pH≈5.6。人类活动把大量硫和氮的氧化物排入大气中,它们被雨水吸收后形成了pH<5.6的酸雨。煤炭中含有硫元素,煤炭燃烧产生SO_2。我国的煤炭含硫量较高,又是一个燃煤大国(煤炭约占能源消费总量的75%),因此,我国的酸雨主要是硫酸型酸雨。硫、二氧化硫、硫酸型酸雨等是九年义务教育和普通高中课程标准实验教科书《化学》中的绿色化学教育内容,它们在教科书中呈现的教学方式多样:化学实验、活动与探究、资料卡片、实践活动等。本文设计了一个符合化学新课程理念和目标 Normal rainfall is acidic, pH≈5.6. Human activities emit large amounts of sulfur and nitrogen oxides into the atmosphere, which are absorbed by the rain and form acid rain at pH <5.6. Coal contains sulfur, coal combustion produces SO_2. China’s high sulfur content of coal, but also a coal-fired power (coal accounts for about 75% of total energy consumption), therefore, the acid rain in our country is mainly sulfuric acid rain. Sulfur, sulfur dioxide, sulfuric acid-type acid rain is nine-year compulsory education and general high school curriculum standard chemistry textbook “chemistry” in the content of green chemistry education in their textbooks presented in a variety of ways: chemical experiments, activities and research, information cards, Practice activities. This article designed a new chemistry curriculum concept and goal
