做化学题目,有时貌似条件不够,实际上出题者将已知条件巧妙地隐藏在题目当中了,一般来说条件“潜伏”的形式至少有如下几种:条件“潜伏”在空气中;条件“潜伏”在水中;条件“潜伏”在物理性质中;条件“潜伏”在化学性质中;条件隐含在溶液体积的变化中;条件“潜伏”在多种无用条件中。 Chemistry topics, sometimes seemingly inadequate conditions, in fact the subject of the known conditions will be cleverly hidden in the title of them, in general the conditions of “latent” in the form of at least the following: Condition “latent ” In the air; Conditions “Latent” in water; Conditions “Latent” in physical properties; Conditions “Latent” in chemistry; Conditions implied in changes in solution volume; Conditions “Latent” In a variety of useless conditions.
