The pH 3 liquid has 1000 times more hydrogen ions than the pH 6 liquid.
The pH 3 liquid has 3 times more hydrogen ions than the pH 6 liquid.
The pH 3 liquid has the same hydrogen ion concentration as the pH 6 liquid.
The pH 3 liquid is less acidic than the pH 6 liquid.
Understanding the Answer
Let's break down why this is correct
The pH scale is logarithmic. Other options are incorrect because The idea that a 3‑unit difference equals 3 times more ions is a linear mistake; Thinking the concentrations are the same ignores the scale’s effect.
