Metachromasia Induced in Cationic Dyes by Iodide Salts
Inorganic salts like NaI and KI induce distinct metachromasia in thiazine dye 1, 9-dimethylmethylene blue (DMMB, 2.0X10-5M ) and cyanine dye pinacyanol chloride (PCYN, 2.0X10-5M). Half plateau values signifying destruction of metachromatic compounds to the extent of 50 % correspond to ̴22 %, and ̴30 % ethanol for DMMB-NaI, and PCYN-NaI systems respectively. Conductometric titrations reveal that DMMB and PCYN bind with NaI in the molar ratio of 1: 1
