Question

related to titration, what is an analyte? the chemical for which the volume is known, but the concentration is not. the point where moles of acid equals moles of base. the chemical for which both the concentration and volu are known. the point during a titration where the color changes for the indicator.

Explanation:

In titration, the analyte is the substance whose concentration is being determined. It is the chemical for which the volume is known (from the titration process), but the concentration is initially unknown. The other options describe different concepts: the point where moles of acid equals moles of base is the equivalence point; the chemical with known concentration and volume is the titrant; the point where the indicator changes color is the end - point.

Answer:

The chemical for which the volume is known, but the concentration is not.
