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.

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.
