For numbers A to E, each of the following items concerns a 0.10 M solution of a  weak  organic base, B. Identify whether the statements are true or false. Shade A if the statement is correct and accurate; if otherwise, shade B.   A. OH-]equals 10 M. B. [B]is much lesser than [HB+]. C. [H3O+]is greater than [HB+]. D. ThepH is  E. [HB+]is approximately equal to [OH-].   For numbers F to J, consider the given case: Blood contains several acid-base systems that tend to keep its pH constant at about 7.40. One of the most important buffer systems involves Carbonic acid and Bicarbonate ion. Ka=4.4 x 10-7.   F. In the carbonic acid-bicarbonate ion buffersystem, which of the following functions as a weak acid? H3CO3+ H2CO3 HCO3- CO32- CO2   G. In the carbonic acid-bicarbonate ion buffersystem, which of the following functions as a conjugate base? H3CO3+ H2CO3 HCO3- CO32-CO2   H. Whatmust be the ratio of bicarbonate to carbonic acid in the blood if the pH is 7.40?  11.05:1 2.95:2…
