Which of the following solutions will have the highest pH, assuming complete dissociation?Remember: pH = -log10[H3O+(aq)], pOH = -log10[OH-(aq)] and pH + pOH = 14.00Group of answer choices0.3 M solution of HI0.8 M solution of Mg(OH)21.4 M solution of LiOH3 M solution of HNO3

The pH of a solution is determined by the concentration of hydronium ions (H3O+) in the solution. The lower the concentration of H3O+, the higher the pH.

1. HI is a strong acid, which means it will completely dissociate in water to form H+ and I-. This will increase the concentration of H3O+ in the solution, thus lowering the pH.

2. Mg(OH)2 is a strong base, which means it will completely dissociate in water to form Mg2+ and OH-. The presence of OH- will decrease the concentration of H3O+ in the solution, thus increasing the pH.

3. LiOH is also a strong base, which will dissociate in water to form Li+ and OH-. This will also decrease the concentration of H3O+ in the solution, thus increasing the pH.

4. HNO3 is a strong acid, which will dissociate in water to form H+ and NO3-. This will increase the concentration of H3O+ in the solution, thus lowering the pH.

Therefore, the solution with the highest pH will be the one with the highest concentration of a strong base. Comparing the concentrations of the strong bases (Mg(OH)2 and LiOH), the 1.4 M solution of LiOH will have the highest pH.
