Homework Answers
Solution :-
The correct option is " 4 " Gas chromatography with FID (flame ionization detector ) .
It is most sensitive technique among all because it distinguishe the species based on their mass and CO2 , NO2 and SO2 all have different mass.
Further explanation
Gas chromatography with TCD detects compounds based on their thermal conductivity. Most of the organic compounds have same thermal conductivity so most of them show very similar peaks hence it is moreover a general technique not very specific and sensitive.
HPLC is better for liquid samples because of liquid mobile phase.

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...

The fizz produced when an AlkaSeltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate, NaHCO3, and a triprotic organic acid, citric acid, H3C6H5O7. The products of this reaction are carbon dioxide gas, water, and sodium citrate. 3 NaHCO3 (aq) + H3C6H5O7 (aq)→ 3 CO2 (g) + 3 H2O(l) + Na3C6H5O7 (aq) In an experiment 1.00 g of sodium bicarbonate and 1.00 g of citric acid are allowed to react. A.Which of the five compounds in...
