Abstract Centered around understanding of the salt solution properties, through experimental inquiry and group cooperative learning, this paper established the thinking method of understanding material property with particle view, integrated the properties of salt solution dispersed in element compounds and electrolyte solutions, and established the relationship between salt solution properties and chemical equilibrium movement principle, redox principle, complex reaction principle and electrochemical reaction principle.While perfecting the core knowledge construction, focusing on the view of particle, the essence of salt solution could be understood well based on the existence of particle in salt solution and its interaction with particle of added reagents. In this way, students could have a relatively high level of perspective, via combining microcosmic, dynamic and balance, to achieve utmost understanding of the whole concept. The main point was exploring the nature of salt solution guided by the view of particle.
