Concept explainers
(a)
Interpretation: Some facts about photography lens are given. The answers are to be stated as per the given conditions.
Concept introduction: Photography lenses contain silver chloride. Silver chloride is light sensitive.
To determine: The explanation for the difference in the fact that, when the light is removed from the decomposition reaction of white silver chloride, the reverse reaction occurs but when pure white silver chloride is exposed to sunlight it darkens and the reverse reaction does not occur in the dark.
(b)
Interpretation: Some facts about photography lens are given. The answers are to be stated as per the given conditions.
Concept introduction: Photography lenses contain silver chloride. Silver chloride is light sensitive.
To determine: An explanation for the reason that, photography lenses do become permanently dark in time.

- The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) . If 25.00 mL of 0.0700 M Na2S2O3 was required to reduce all the iodine produced by the bleach back to iodide, what is the mass percent of NaClO in the bleach?arrow_forwardWrite balanced chemical equations for the following reactions: (a) cadmium burned in air. (b) elemental cadmium added to a solution of hydrochloric acid. (c) cadmium hydroxide added to a solution of acetic acid, CH3CO2Harrow_forward7.
