We are being asked to determine the pH of the solution.

The **reaction quotient, Q**, can be calculated like an equilibrium constant with the formula shown below:

$\overline{){\mathbf{Q}}{\mathbf{=}}\frac{\mathbf{products}}{\mathbf{reactants}}}$

**Let’s calculate the Reaction Quotient (Q) using the given concentrations:**

What pH is needed to produce this value of *Q* if the concentration and pressure values are

[Br2] = 2.50×10^{−4}*M* ,

[Br− ]= 11.90*M* ,

[SO42−] = 8.15*M* , and

*P*SO2 = 1.25×10^{−5 }atm

Express your answer numerically to two decimal places.

*Q *= 1.6×10^{−26}
