铝和稀盐酸反应过程中产生大量的灰色物质,通过实验获取灰色物质并对其进行不同条件下的探究,用实验探究对理论假设提供依据,增强实验对化学教学的指导功能。 A large amount of gray matter was produced during the reaction between aluminum and dilute hydrochloric acid. The gray matter was obtained through experiments and explored under different conditions. The experimental hypothesis was provided to provide theoretical basis for the hypothesis and to enhance the guiding function of the experiment on chemistry teaching.
