Question

identify the location where you would expect to find a substance with the lowest concentration of h⁺ ions. click or tap the appropriate place in the image.

Explanation:

Step1: Recall pH and H⁺ relation

The pH scale is related to \([H^+]\) by \(pH = -\log_{10}[H^+]\). Lower \([H^+]\) means higher pH.

Step2: Identify highest pH

On the scale, pH 14 is the highest (top of the blue region, labeled 14's position). Higher pH means lowest \([H^+]\).

Answer:

The location with the lowest \(H^+\) concentration is at the top of the scale, corresponding to pH 14 (the blue - topped area or the position labeled 14).
