Use numbers to indicate the order of the steps in the titration process. _continue adding base from the buret until a color change is observed in the erlenmeyer flask. _add three drops of chemical indicator to the acid. rinse the buret with standardized base solution, and clean and rinse the buret with water. _stop addition of base from the buret, and read and record the final buret volume. _read and record the initial buret volume. _begin adding base from the buret to the acid. _fill the buret with standardized base solution. _use a clean and rinsed volumetric pipet to transfer a known volume of acid to an erlenmeyer flask.

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
