(a) Interpretation: The below compounds should be ranked in order of increasing acid strength (from weakest to strongest) CH 3 COOH, CH 3 OH, C 6 H 5 OH (Phenol) Concept introduction: As per the Bronsted-Lowry theory of bases and acids: Proton acceptors are bases and Proton donors are acids. Molecules which can either accept or donate the proton are known as amphiprotic. So, an amphiprotic act as either base or acid. Hydrogen sulfate ion, hydrogen carbonate ion, amino acids and water are common illustrations of amphiprotic molecules. Because they might donate the proton, all of the amphiprotic species have hydrogen atom.

The U. S. Environmental Protection Agency (EPA) sets
limits on healthful levels of air pollutants. The
maximum level that the EPA considers safe for lead air
pollution is 1.5 μg/m³
Part A
If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs? (Assume a total lung
volume of 5.40 L.)
ΜΕ ΑΣΦ
= 2.35 1013
?
