In the present study, a very prominent cost effective sol-gel method was used to amalgate the ethyl cellulose-tin(II) hydrogen phosphate (EC-SnHPO4), an organic–inorganic composite material with certain acidic condition practiced in a conductivity system. The physical characterization of the material was described by the UV-Vis and FTIR study. The different monovalent electrolytes such as KCl (aq) and NaCl (aq) at diverse temperature range was employed to measure the conductivity of EC-SnHPO4 and also for the concentration to explore between affinity of conductivity and electrochemical properties of the material. From the study, the conductivity was established to be less for K + than Na + . For such process in addition, the different parameters such as ionization potential, oscillator strength, transition dipole moment, resonance energy, and transition energy were investigated. Finally, the anticancer effect against the MCF-7 breast cancer cell line and the antibacterial activity against two different bacterial strains show the potential pharmacological activity of the EC-SnHPO4 towards medical applications.
