With which of the following ions would you expect a color change after the addition of acidified potassium permanaganate? Select all that apply.
- nitrite
- nitrate
- carbonate
- sulfite
- sulfate
- phosphate
- chromate
Homework Answers
The only two species that would give color change are
nitrite ( NO2- )
sulfite ( SO3-2 )
This is because as KMno4 is oxiding agent in this reaction so it do not behave as O.A untill the species which can be oxidized . Here in these 2 species the Oxidation state of N is +3 and for S is +4 so , it can be able to reduce or oxidize to +5 and +6 respectively and we obssrve color change while other are already present in maximum oxidation state . So it can reduce not oxidize.

Following the addition of naphthylamine to a tube of nitrate broth culture, no color change occurs. Zinc dust is then added, and again no color change occurs. A gas bubble is observed in the Durham tube. These results indicate that: more testing is required. denitrification has occured. nitrate has been reduced to nitrite. nitrate has likely been converted to ammonia. nitrate has not been utilized.

. Write the three equations and identify the spectator ions in the following mixtures (your instructor may assign different or additional ones): a. Hydrochloric acid and silver nitrate. b. Silver nitrate and sodium carbonate. c. Potassium chromate and lead (II) acetate. d. Sodium sulfate and barium chloride. e. Lead (II) acetate and ammonium chloride

Questions: After adding Nitrate Reagent A and B, there was no red color change. You then added a pinch of zinc powder with a formation of a red color. What category of nitrate reduction, would this microbe be? Explain how this red color change occurred? Denitrification part of the nitrogen cycle. Some microbes use this pathway anaerobically to convert nitrates (NO3- ) to nitrogen (N2) gas. Other bacteria in anaerobic conditions, use what is called a Dissimilatory nitrate reduction to...
