You are in charge of a combustion furnace. The furnace is fed an air stream and a methane stream which is combusted to produce heat that is used to boil water and produce steam for your plant. The combustion of fuels using an air stream which contains nitrogen generally produces significant amounts of NO, compounds which are an air pollutant, so the exhaust gases must generally be removed through various processes. In this case, your furnace exhaust is passed through...

What is
acidity and what are the compounds controlling it?
Acidity is a measure of
the concentration of hydrogen ions (H+ or protons) in a solution. We
use pH (potential of H+) as a scale of acidity and this can be
calculated as below:
pH =
-log10[H+] =
log10
(1/[H+])
Q1. Figure 10.3 shows you a range
of pH in some common liquids. Pick 2 liquids (one each from acidic
and basic solutions) and compare the molarity of
[H+] in...
