Abstract:
A novel hydrazone, 1,3-bis (2-formylphenoxy) propane bis (2,4-dinitrophenyl hydrazine) (S) has been synthesized and characterized by the NMR, IR, CHNS, UV-Vis, Raman, TEM and XPS analysis. Upon the addition of monohydrogen phosphate (MHP) ion, sudden color change from light yellow to dark violet has occurred. The binding constant of S-MHP was determined by Hill plot. Hydrazone also showed potential response with MHP ion. A number of polymeric membrane electrodes (PME) and coated graphite electrode (CGE) were also fabricated and found that the CGE has revealed better results in comparison to PME in terms of the detection limit of 7.58 × 10(-9) mol L(-1) and Nernstian response.

Using the ICE table and substituting the Kb value, we calculate the initial pH of 50 mL of 0.1 M ammonia to be 11.11. Addition of 25 mL of 0.1 M hydrochloric acid to this solution of ammonia results in a buffer with an equal concentration of ammonia and ammonium ions. The pH of this buffer can be calculated by substituting these...
