Question 2 (1 point) Match the following descriptions or examples corresponding term. More than one description or example may be with each term If a description or example does not match up given terms, select "None of the above" KHP solution a substance from which a standard solution can be prepared directly picks up water from the atmosphere a substance from which an exact concentration of solution can be prepared by weighing it out, and then adding water to a specific volume 1 when the volume of acid equals 2.

Explanation / Answer

KHP solution is the standard solution

a substance which a standard solution can be prepared directly is a primary standard

picks u water form atm --> hygroscopic materials

substance in which an exact concentration can be prepared by wieghinig -> primary standard

when volume of acid = volume of base = none

phenolphthaleisn = none of above = it is an indicator

when 2 reactnats = stoichioemtrically equivalnet = equivalence point

water = none, it is the solvent

must be 99.9% --> primary standard

solution known concentration = standard solution

not necessarly at pH = 7 = equivalence point
