What is a solution with a pOH value of  considered?Question 3Select one:a.baseb.acidc.saltd.neutral

To determine what a solution with a specific pOH value is considered, we can analyze the relationship between pOH, pH, and the nature of the solution.

Understanding pOH and Its Relation to Acidity/Alkalinity

1. Definition of pOH: The pOH of a solution is a measure of its hydroxide ion concentration $[\text{OH}^-]$. It is given by the formula: $\text{pOH} = -\log[\text{OH}^-]$

2. Relation Between pH and pOH: The pH and pOH values of a solution are related through the following equation at 25°C: $\text{pH} + \text{pOH} = 14$

3. Classification:

   • A neutral solution has a pH of 7, and consequently, a pOH of 7 as well.
   • An acidic solution has a pH less than 7 (thus pOH greater than 7).
   • A basic solution has a pH greater than 7 (thus pOH less than 7).

Analyzing the Given Choices

• If the pOH value is less than 7, the solution is considered a base.
• If the pOH value is greater than 7, the solution is considered an acid.
• If the pOH value is exactly 7, the solution is considered neutral.

Final Conclusion

Given that we need to identify what a specific pOH value signifies without knowing the exact number, we can reason through the options:

• If the pOH is 7, then the answer is neutral.
• If the pOH is less than 7, then the answer is base.
• If the pOH is greater than 7, then the answer is acid.

Thus, without the specific pOH value, the type of solution cannot be definitively categorized. However, you can determine from the pOH value whether the solution is a base, acid, salt, or neutral based on the concepts explained.
