    The effectiveness of the halide ions Cl-, Br-, and I- as restrainers is roughly proportional to the ratios of the solubility products of the corresponding silver halide; AgCl = 1.8 x 10-10, AgBr = 5.3 x 10-13, AgI = 8.3 x 10-17, . Thus KI is 1000X more effeftive than KBr which in turn is 1000X more effective than NaCl.
