Spectrophotometric study of stability constants of Ni (ii)‎-famotidine complex at different temperatures

الملخص EN

Famotidine is histamine of H2-receptor antagonist.

The formation of Ni (II) complex with famotidine has been studied spectrophotometricaly at an absorption maximum of 426 nm at different temperatures.

The data shows that Ni (II) and famotidine combine in the molar ratio of 1:4.

The stability constants of the complex were calculated to be 1012 x 1.50-1.25 by continuous variation method and 3.0–3.20 × 1012 by mole ratio method at 25 and 40 °C respectively.
