The ph of a person's blood is given by ph = 6.1 + log10 b - log10c, where b is the concentration of bicarbonate, which is a
base, in the blood and c is the concentration of carbonic acid in the blood.
use the quotient property of logarithms to simplify the formula for blood ph.
a. ph = 6.1 + log10 10/c
b. ph = 6.1 + log10 b/c
c. ph = 6.1 + logc b/10
d. ph = 1/6.1 + log10 b/c
