The given solution has a pH of 9.7. This means it is basic in nature. We know that when a weak acid (represented by HS1U1B) reacts with water, it forms its conjugate base (represented by S1U1B0O) and H+ ions. Similarly, when a weak base (represented by S1U1P0) reacts with water, it forms its conjugate acid (represented by HS1U1P) and OH- ions. The pH of a solution depends on the concentration of H+ ions in it. In a basic solution, the OH- ion concentration is high and the H+ ion concentration is low.
Thus, we can conclude that in the given solution, there is a significant amount of S1U1B0O and S1U1P1 ions, indicating that it contains the weak base and weak acid in reasonable concentrations. Therefore, the best option is C, which represents a mixture of weak acid and weak base in equal concentrations.
