What is the pH of 0.1m k3po4?

Answer 1

To determine the pH of a 0.1 M solution of K₃PO₄ (potassium phosphate), we first recognize that it dissociates completely in solution to yield K⁺ and PO₄³⁻ ions. The phosphate ion (PO₄³⁻) can act as a weak base and undergo hydrolysis, producing hydroxide ions (OH⁻) and resulting in a basic solution. The pH would typically be above 7, and for a 0.1 M K₃PO₄ solution, the pH is expected to be in the range of approximately 11-12, depending on the extent of hydrolysis.
