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 a.What is the...

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...
