Abstract
pK values of Methyl-1-phenyl-3-(2'-hydroxy aryl) pyrazole-5-carboxylate. [MPHAPC] in 70% ethanol-water mixtures and log K values of alkaline earth metal (Sr) and rare earth metals (Pr, Nd, Tb) chelates has been investigated pH metrically. It showed the formation of 1:1 and 1:2 complexes in the pH range 2.5 to 5.5.
