Abstract
An acoustic absorption band with an 0.5-0.8 MHz frequency was observed for concentrated solutions of magnesium, calcium, and barium thiocyanates. The whole contour of the hand was measured, and its principal parameters (relax ation frequency and maximum absorption amplitude) were determined with high accuracy. The absorption band was assigned to the MeSCN+ + (SCN)(-) revers ible arrow Me(SCN)(2) reaction of formation of neutral particles for magnes ium, calcium, and barium thiocyanates. The kinetic parameters of this react ion were determined.
