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 11.65 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.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
