Interactions of some amino acids with aqueous manganese chloride tetrahydrate at TÂ =Â (288.15 to 318.15)Â K: A volumetric and viscometric approach

► The transfer values are positive and increase with concentration of MnCl2·4H2O. ► MnCl2·4H2O has stronger dehydration effect than CdCl2 and ZnCl2. ► Glycine acts as structure breaker and l-leucine acts as structure maker.
