• The coefficients of the viscosity of concentrated aqueous solutions of 1–1 type electrolytes were measured at room temperature. Judging from the relationship between relative viscosity and concentration the electrolytes would be classified into two groups. One is normal and the other shows negative viscosity.It is the linear term that makes the most predominent contribution in the dilute range. We analyzed its factor by the use of Broersma's concept of local viscosity. From the expression obtained, a condition of negative viscosity was derived as 6 in approximation. According to our interpretation, negative viscosity does not result from individual characters of ions of each electrolyte in question, but from delicate correlations between the local viscosities of neighboring hydration layers.
