Which of the following is/are the correct statement(s) about sodium th...
A . An antichlor is a substance used to decompose residual hypochlorite or chlorine after chlorine-based bleaching, in order to prevent ongoing reactions with, and therefore damage to, the material that has been bleached. Antichlors include sodium bisulfite, potassium bisulfite, sodium metabisulfite, sodium thiosulfate, and hydrogen peroxide

B. silver halides (eg.: AgBr ) dissolve upon the action with aqueous thiosulfate.
2 S2O32− + AgBr → [Ag(S2O3)2]3− + Br−
so we can remove AgBr , a component of photographic emulsions, using sodium thiosulfate.

C. the thiosulfate anion reacts stoichiometrically with iodine in aqueous solution, reducing it to iodide 
2 S2O32− + I2 → S4O62− + 2 I−
because of its excellent shell life and quantitative nature of this reaction it is used in the titration of iodine.

D. the oxidation state of sulphur is -2 and+6 in sodium thiosulfate.

The answers are option A , B , C only. (not D)

Similar Class 12 Doubts

Images are the core of society today; they have become the means of massive communication and, therefore, the essence of daily life. Humans have become homus photographicus. Almost every person has a camera, whether it is in a cellphone, iPad, tablet, point and shoot or any other device. People have learned to express emotions, ideas and concepts through images regardless of its complexity. Photos may be digital images but not every image is a photograph. In general, the image is defined as a figure, the representation of something. That is, the copy of an object, a mental representation is subject to cognition and interpretation.The material images, under their production scheme, are prone to depict the world on a canvas, the medium determines how people look, read, sing and tell stories.Additionally, the narratives are considered to be truthful because, in order to photograph an object, it has to exist; it has a referent, contrary to painting, where the artist may create chimeras based on imagination. Nonetheless, the veracity of a picture may be questioned since it could be staged or transformed into something else, even something that is not as it appears in reality. For example, a portrait may be an idealistic version of a person, an alter ego or simply not the subject as known in daily life. To illustrate further, the case of Hippolyte Bayard becomes interesting to mention. In 1840, Bayard photographed himself as a drowned man, and people who saw the picture believed it was real. At the time, these images were believed to be real because a mechanic device, a camera, had taken them. In this way, Bayard created an alternative reality, where he was found dead.Q. Which of the following is true in the context of the passage?
