中文简介: | 你想知道你喝的水里有什么吗?这门免费课程,饮用水中可能存在哪些化合物?,检测饮用水中存在的化合物。水中某些阴离子的含量过高会导致环境污染和健康问题。阳离子也很重要。例如,钙盐有助于提高水的硬度,水处理使用铝化合物。此外,氧化剂,如臭氧或氯,在水的消毒中至关重要。本OpenLearn课程侧重于元素周期表第13至18族p区元素的化学。 |
课程简介: | Do you want to know what’s in the water that you drink? This free course, What chemical compounds might be present in drinking water?, examines the chemical compounds that occur in drinking water. A high level of certain anions in water can cause environmental pollution and health problems. Cations are also important. For example, calcium salts contribute to the hardness of water and water treatment uses aluminium compounds. Additionally oxidising agents, such as ozone or chlorine, are vital in the disinfection of water. This OpenLearn course focuses on the chemistry of the p-block elements in Groups 13 to 18 of the Periodic Table. |
