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.

pOH = 2.35

Explanation:

The pH scale is a way to measure the concentration of H⁺ ions in a solution. On the other hand, pOH is a way to refer to the concentration of OH⁻ in a solution. pH and pOH are related through the following equation:

pH + pOH = 14

If pH = 11.65, then

pOH = 14 - pH = 14 -11.65 = 2.35

When pH > 7 and pOH < 7, the solution is basic.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
