- Calculate the pH of a solution prepared by mixing 49.0 mL of butyric acid, HC4H7O2, with 6.15 g of KOH in water. The following data about butyric acid may be helpful: density=0.9595g/mL;K a =1.54105(a) Acid rain is no threat to lakes in areas where the rock is limestone (calcium carbonate), which can neutralize the acid. Wherethe rock is granite, however, no neutralization occurs. How does limestone neutralize acid? (b) Acidic water can be treated withbasic substances to increase the pH, although such a procedure is usually only a temporary cure. Calculate the minimum mass oflime, CaO, needed to adjust the pH of a small lake (V = 4 x 109 L) from 5.0 to 6.5. Why might more lime be needed?Polymers are not very soluble in water, but their solubility increases if they have charged groups. (a) Case in, a milk protein,contains many —COO⁻ groups on its side chains. How does the solubility of casein vary with pH? (b) Histones are proteins es-sential to the function of DNA. They are weakly basic due to the presence of side chains with —NH2 and =NH groups. How does the solubility of a histone vary with pH?

- The simplest amino acid is glycine, H2NCH2CO2H. The common feature of amino acids is that they contain the functional groups: an amine group, –NH2, and a carboxylic acid group, –CO2H. An amino acid can function aseither an acid or a base. For glycine, the acid strength of the carboxyl group is about the same as that of acetic acid, CH3CO2H, and the base strength of the amino group is slightly greater than that of ammonia, NH3.(a) Write the Lewis structures of the ions that form when glycine is dissolved in 1 M HCl and in 1 M KOH.(b) Write the Lewis structure of glycine when this amino acid is dissolved in water.he pH of an aqueous solution of 0.355 M acetylsalicylic acid (aspirin) , HC9H7O4, is .An episode of CSI: Miami had a deceased victim floating in a swimming pool contaminated with sodium hydroxide. The concentration was high enough to eat through glass. When the CSI guys realized it was alkali (ie., a base) they knew they needed to neutralize it in order to retrieve the body so they sent one of their team to a local store for vinegar. They proceeded to pour vinegar from a couple of gallon jugs into the pool, dropping the pH from 14 to exactly 7.0 all within a few seconds, and without any stirring! The volume of swimming pool is 100,000L. Vinegar is approximately a 1.0 M of acetic acid, HC2H3O2, a monoprotic acid. A pH of 14 is equivalent to 1.0 M solution of sodium hydroxide,NaOH. Using your knowledge of chemistry, comment on whether or not the events described in the episode of CSI: Miami could take place
