Question

identify the option below that is a characteristic of acidic solutions.
select the correct answer below:
$h_{3}o^{+}poh levels greater than 7 at $25^{circ}c$
poh levels less than 7 at $25^{circ}c$
poh levels of 7 at $25^{circ}c$

Explanation:

Step1: Recall the relationship between \(pH\), \(pOH\) and solution acidity

At \(25^{\circ}C\), \(pH + pOH=14\). For acidic solutions, \(pH<7\).

Step2: Derive the \(pOH\) value for acidic solutions

If \(pH<7\), then \(pOH = 14 - pH>7\) (since \(pH<7\)).

Step3: Analyze other options

• For \([H_3O^{+}]<[OH^{-}]\), the solution is basic.
• If \(pOH<7\), then \(pH = 14 - pOH>7\) (solution is basic).
• If \(pOH = 7\), then \(pH=7\) (solution is neutral).

Answer:

pOH levels greater than 7 at \(25^{\circ}C\)
