Quinine, an alkaloid derived from a tree that grows in tropical rain forests, is used in the treatment of malaria. Like all alkaloids, quinine is a sparingly soluble weak base: 1.00 g of quinine will dissolve in 1.90 × 10² L of water.

What is the pH of a saturated solution of quinine?

The number of significant digits is set to 2; the tolerance is +/-4%

A 27.4 mL sample of saturated quinine is titrated with 0.00843 M HCl solution. What is the pH at the stoichiometric point of the titration?

Quinine is a natural product extracted from the bark of the cinchona tree, which is native to South America. Quinine is used as an antimalarial agent. When 3.10 g of quinine is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 7.95 °C. The freezing point and Kf constant for cyclohexane can be found here. Calculate the molar mass of quinine. https://sites.google.com/site/chempendix/colligative

3) A sticky goo oozes mysteriously from the rare wazoo tree, which grows only on the farm of Wolf Molder, just outside of Pullman, Washington. This goo, when smeared on the face, results in a tightening of the skin and the elimination of fine lines. Wolf bottles the goo at a cost of $2 per bottle and sells it to Donna Scali at a wholesale price of $w per bottle. Donna sells the goo to the general public over the...

When a plant grows, the atoms used come from carbon dioxide in the air and water. Plants are able to accomplish this through the process of photosynthesis, cellular respiration and biosynthesis of macromolecules. Where does the energy come from that allow plants to synthesize the necessary biological macromolecules that allow it to grow? Hint: It is NOT from sunlight. Explain your answer.
