SELECT correct responses only 1) Volume percent (v/v%) is temperature-independent. 2) There are three major approaches to expressing solution concentration in terms of percent concentration: weight percent, volume percent, and weight/volume percent. 3) Weight/volume percent (w/v%) is a unit-less quantity. 4) The term 'percent' refers to 'parts per thousand'. 5)A standard solution is a reagent of known concentration that is used to carry out a volumetric titration. 6) The endpoint of a titration is the theoretical point reached when the amount of added titrant is chemically equivalent to the amount of analyte in a sample. 7) A substance that changes color in response to chemical equivalence is known as an indicator. 8) Given a sufficiently diligent and experienced experimenter, it is sometimes possible to reach a titration volume error value of 0.
