【Abstract】 Two inorganic binary solutions,AgNO3 solution and KI solution,were prepared.The refractive index and concentration of two solutions were concerned in the experiment.Based on a calculating expression n=1+∑(ρMDM),the refractive index were calculated and compared with the measured refractive index to examine the precision of the expression above.The result demonstrated the sound correspondence between calculated values and measured values.The maximized errors were: Δnc(AgNO3)=0.02%,Δnc(KI)=0.05%.The expression provides a good way to detect the concentration of solutions through measuring the refractive index of them.更多还原
