苏教版《实验化学(选修)》教材在“牙膏和火柴头中某些成分的检验”课题中利用火柴头的燃烧实验检验硫元素。在开展含硫火柴头燃烧实验的教学时,基于操作安全简捷、药品用量少、实验绿色化等方面的考量,对该定性实验进行了再创新。同时利用创新后实验密闭性好的优点,进一步定量测定火柴头中硫元素的质量。
The Soviet version of “experimental chemistry (elective)” textbook in the “toothpaste and match head test of certain components ” subject to the use of match head combustion test elemental sulfur. In carrying out the teaching of sulfur-containing match-head combustion experiment, the qualitative experiment was re-innovated based on the considerations of simple and safe operation, less dosage of medicine and green experiment. In the meantime, the quality of sulfur element in match head was further quantitatively determined by taking advantage of the good confinement of experiment after innovation.
