Chemical deposition refers to the process of precipitation and accumulation of substances transported in the form of colloid solution and true solution in water medium after they reach the appropriate place when chemical conditions change
Among them, colloid solution refers to the solution containing a certain size of solid particles or polymer compounds, real solution refers to a higher transparency of aqueous solution
Dry early climate area, the lake water rarely leakage, evaporation effect makes the lake sodium chloride increase, accumulation, become salt water lake
