If a solution has a pH of 10.35, what is the pOH?
What is the relationship between pH and pOH? How can we calculate the pOH of a solution with a pH of 10.35?
The pH and pOH are logarithmic scales used to measure the acidity and basicity of a solution, respectively. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral, pH less than 7 is acidic, and pH greater than 7 is basic. The pOH scale is the reverse of the pH scale, where a pOH of 7 is neutral, pOH less than 7 is basic, and pOH greater than 7 is acidic.
To find the pOH, we can use the equation: pOH = 14 - pH. In this case, the pH is 10.35. Substituting this value into the equation, we get pOH = 14 - 10.35 = 3.65. Therefore, the pOH of the solution is 3.65.
Understanding pH and pOH:
pH and pOH Scales: pH and pOH are measures of the concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻) in a solution. pH measures the concentration of H⁺ ions, while pOH measures the concentration of OH⁻ ions.
Calculating pOH from pH:
Step 1: Determine the given pH value. In this case, the pH is 10.35.
Step 2: Use the relationship pOH = 14 - pH to calculate the pOH value.
Step 3: Substitute the pH value into the equation: pOH = 14 - 10.35 = 3.65.
Therefore, the pOH of the solution with a pH of 10.35 is 3.65.
