27) Why is the increasing amount of carbon dioxide being taken up by the oceans a cause for concern? a) More carbon dioxide causes an increase in carbonic acid (H2CO3), which leads to a decrease in the concentration of carbonate ion (CO32 ). b) he buffering action of carbonic acid (H2CO3) causes the pH of seawater to rise. c) There is no cause for concern. Carbonic acid (H2CO3) is an excellent buffer and will help keep the pH of seawater constant. d) More carbon dioxide causes an increase in carbonic acid (H2CO3), which leads to an increase in the concentration of carbonate ion (CO32 ).
28) Adding a base tends to __________ of a solution.
29) A solution at pH 6 contains __________ than the same amount of solution at pH 8.
30) Which of the following dissociations is that of an acid?
31) Why are cell membranes composed primarily of hydrophobic molecules? a) Cell membranes must be hydrophobic in order to allow polar and charged molecules to enter and leave the cell b) Cell membranes must be composed of polar molecules in order to interact with the aqueous solutions inside of cells. c) In order to perform their function of separating the aqueous solutions outside of cells from the aqueous solutions inside of cells, cell membranes cannot be soluble in water. d) In order to maintain a proper pH, cell membranes must be hydrophobic.
32) How does the polarity of water contribute to its ability to dissolve so many substances?
33) Sweating has a cooling effect because of water's high __________.
