Final answer:
In Phosphate Buffered Saline (PBS), the ions produced are sodium ions and phosphate ions due to the dissociation of sodium phosphate, and chloride ions from the dissociation of sodium chloride.
Step-by-step explanation:
The ions being produced by Phosphate Buffered Saline (PBS) process, assuming that each of the chemical compounds dissociates into their constituent parts once they are dissolved in water, are sodium ions, phosphate ions, and chloride ions. Among the choices given, sodium ions and chloride ions are present due to the dissociation of sodium chloride (NaCl), which will break down into Na+ and Cl-. Phosphate ions (PO43-) are released from compounds such as sodium phosphate (Na3PO4).
If we consider the solubility product of calcium phosphate, we note that calcium ions (Ca2+) and phosphate ions (PO43-) are indeed produced in such a dissolution but are not typically relevant to the formulation of PBS. PBS primarily contains sodium phosphate, which includes sodium ions (Na+) and phosphate ions (PO43-), along with sodium chloride, which contributes sodium ions (Na+) and chloride ions (Cl-). Thus, the correct answer is a. Sodium ions, Phosphate ions, and Bicarbonate ions. However, the bicarbonate ions are not mentioned in the dissociation process but are usually added to PBS for pH stabilization.
