FREE Expert Solution

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:

Q=productsreactants


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] = 2.50×10−4M ,

[Br− ]= 11.90M ,

[SO42−] = 8.15M , and

PSO2 = 1.25×10−5 atm 

Express your answer numerically to two decimal places.

= 1.6×10−26
