Unsure on both 4.8 and 7.8. Need to see calculations.

4. The body makes use of bile acids to solubilize fatty substances that pass through the digestive system. This allows the body to absorb hydrophobic nutrients via the small intestine. Shown below is the bile acid cholic acid; note the general hydrophobic character of the cyclic portion of the molecule: pKa=4.8 Given the pKa of the acid (pKa=4.8), what is the ratio of the deprotonated form to the protonated form at each given pH ? At pH4.8 ? At pH7.8
