Question

Part D In the simulation, open the Custom mode. The beaker will be filled to the 0.50 L mark with a neutral solution. Set the pH to 10.45 by using the green arrows adjacent to the pH value indicated on the probe in the solution. Once you adjust the pH, note the corresponding OH ion concentration in M as given in the graphic on the left side of the simulation. Make sure to select the option "Concentration (mol/L)" above the graphic. Select on the Logarithmic scale below the graphic. Find the pOH of the solution Express your answer numerically to two decimal places. View Available Hint(s) 2 Submit Previous Answers X Incorrect; One attempt remaining; Try Again

Explanation / Answer

pH and pOH of a solution are interrelated to each other by a relationship as follows:-

pH+pOH=14

pH is given as 10.45 and therefore we can find the pOH from the above relationship.

10.45+ pOH=14

pOH=14-10.45

pOH= 3.55

Hence , the pOH comes out to be 3.55
