The "end point" is the measured volume of solution that yields a change in appearance, usually int he form of a change in an indicator. a. analyte b. titrant c. precipitate d. solute

A- Analyte

The end point is the measured volume of analyte solution that yields a change in apperance,usually in the form of change of color in an indicator. A titrant is added to this analyte in order to arrive at the equivalence point,(where the concentration of H+ ions is equal to the concentration of OH- ions) and determine the concentration of the analyte. The end point is an indication that the equivalence point has been achieved.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

let that person have a turn to speak : )
