44 views1 pages
Document Summary
C127 lecture 9 notes- calcium content of milk and orange juice. Learning goals: use titration to determine quantity of a species in aqueous solution, properly use/read a buret, be able to use parts per million (ppm) as unit of concentration, be able to use pca for concentration. Recall from milk lab: calcium and phosphate ions not precipitated: other methods can be applied to species in solution. Titrations- using chemical reaction between 2 species and stoichiometry of the reaction to determine a concentration (ph: (cid:1829)+2+(cid:1831)(cid:1830) 4 (cid:1829)(cid:1831)(cid:1830) 2, edta molecule, edta binds to calcium in 1:1 fashion; octahedral structure around (cid:1829, when in presence of (cid:1829)+2, red. Indicator- changes color in this case: when no calcium present, blue. Getting good data: accurate volumes of milk/oj samples- use class a glassware, accurate readings of buret. Estimate 1 more decimal place than marks give (hundredths)
