要懂得酵素,先須瞭解接觸剂。大家都知道硫酸是三氧化硫加水後製成的,而三氧化硫則由二氧化硫和空氣中的氧結合,後一步驟如果不加點白金粉末,反应便進行得太慢,在這里白金粉末本身不參加反應,而是加速化学的反應。在实驗室中,如果要保存過氧化氫(即雙氧水)不分解,便應该小心不讓灰尘進去,因為灰尘可以当作接觸劑,來促進過氧化氫的分解。當開瓶子的時候分解出 To understand the enzyme, we must first understand the contact agent. We all know that sulfuric acid is made of sulfur trioxide added to water, while sulfur trioxide by the sulfur dioxide and oxygen in the air, the next step if you do not add some platinum powder, the reaction will proceed too slowly, where the platinum powder itself is not To participate in the reaction, but to speed up the chemical reaction. In laboratories, if hydrogen peroxide (ie, hydrogen peroxide) is to be preserved without decomposition, care should be taken not to allow dust in as dust can act as a contact to promote the decomposition of hydrogen peroxide.
