Expert Solution
(a) when an ionic salt like NaCl is dissolved in water then it try to solvate the water molecule by attracting water molecule through its ions which in turn decreases the affinity of water with oxygen which thus result in lowering of oxygen level.
(b) As depth increases temperature of water decreases and we all know that colder water contain more oxygen dissolved in it then warmer water hence it contains increases therefor.
(c)
As more algae and plants grow, others die.This dead organic matter becomes food for bacteria that decompose it.With more food available, the bacteria increase in number and use up the dissolved oxygen in the water thus decreases the amount of oxygen in water.

A water sample obtained from the neigborhood pond was analyzed
for dissolved oxygen content. A volume of 300 mL, with temperature
21 degrees Celsius, was analyzed using the Wrinkler method shown in
the simulated lab material. It took 15.0 mL of 0.01 mol/L Na2S2O3
solution to reach titration end point.
*Note: Na2S2O3 solution is the source of S2O32- ions for the
titration reaction.
In the succeeding questions, provide the following values
required. Take note of the units

The quantity of dissolved oxygen is a measure of water pollution
in lakes, rivers, and streams. Water samples were taken at four
different locations in a river in an effort to determine if water
pollution varied from location to location. Location I was 500
meters above an industrial plant water discharge point and near the
shore. Location II was 200 meters above the discharge point and in
midstream. Location III was 50 meters downstream from the discharge
point and near...

The Winkler method for dissolved oxygen in water is based on the
rapid oxidation of solid Mn(OH)2 to Mn(OH)3
in alkaline medium. When acidified, the Mn (III) readily releases
iodine from iodide. A 240.-mL water sample, in a stoppered vessel,
was treated with 1.10 mL of a concentrated solution of NaI and NaOH
and 1.10 mL of a manganese(II) solution. Oxidation of the
Mn(OH)2 was complete in about 1 min. The precipitates
were then dissolved by addition of 2.20 mL...

The water used in this experiment is sparged with nitrogen to
remove any dissolved oxygen. The proton-coupled reduction of oxygen
is shown in the following half reaction:
O2 + 4 H+ + 4 e- = 2 H2O
a.Explain why sparging a solution with N2to remove dissolved
oxygen is an equilibrium process.
b.Using the half reaction above, write the balanced equation for
the reaction of ascorbic acid with oxygen. Show your work.
c.If you didn’t know whether or not O2is capable...

What is the level of saturation of lake water containing 10.8
mg/L dissolved oxygen at 14o C. Note that KH
(14o C)= 1.53*10-3 mol/L*atm.
I know that
[O2]eq=KH*PO2 but I am
unsure how I should approach this problem otherwise.
