It happens because the bond between potassium and bromide is ionic. Based on the results obtained, it can be considered that the DTC, MSiNPs, and MSiNP-DTC did not show remarkable toxicity to aquatic organisms at the range of concentrations tested. This is because HCl is a much stronger acid than water and happily sheds its proton in solutions with acidity far greater than that of water, which has a neutral pH of 7.

The characterization of the obtained MSiNPs shows that the synthesized nanoparticles had homogeneous sizes suitable for drug delivery systems. Explanation: When potassium bromide is dissolved in water, it gets dissociated into potassium ions and bromide ions. (Pages 613 - 616). Concerning the loading efficiency of the MSiNPs, the DTC was successfully adsorbed to the MSiNPs, and these results suggest that MSiNPs have potential for the delivery of DTC in particular, and possibly for wider use in drug delivery applications, improving the stability and overcoming the low water solubility of Schiffs dithiocarbazate bases. Explanation: When potassium bromide is dissolved in water, it gets dissociated into potassium ions and For carbon tetrachloride, the boiling-point constant is 5.03C kg/mol, and the boiling point of pure carbon tetrachloride is 76.50C.
