Question

question 7 (1 point)
what is the ph of a solution with a poh of 6.2?
6.2
8.8
7.8
7.2

Explanation:

Step1: Recall the relationship between pH and pOH

The formula is \(pH + pOH=14\).

Step2: Solve for pH

Given \(pOH = 6.2\), then \(pH=14 - pOH\). Substitute \(pOH = 6.2\) into the formula: \(pH=14 - 6.2\).

Answer:

\(pH = 7.8\), so the correct option is \(7.8\).
