Interpretation:
The reason should be determined for expected reasonably the chemistry of dichromate ion which involves mostly in
Concept introduction:
The term oxidation refers to the loss of electrons by a chemical species and the term reduction refers to the gain of electrons by a chemical species. Oxidation -reduction reactions are those

- Although the ClO4- and IO4- ions have been known for along time, BrO4- was not synthesized until 1965. The ion wassynthesized by oxidizing the bromate ion with xenon difluoride,producing xenon, hydrofluoric acid, and the perbromateion. (a) Write the balanced equation for this reaction.(b) What are the oxidation states of Br in the Br-containingspecies in this reaction?arrow_forwardThe equilibrium constant for the disproportionation copper(I) shown below is 1.81 x 106. If the copper(I) ion is dissolved in dimethylsulfoxide as a solvent the equilibrium constant is only approximately 2. Provide an explanation for the observation.arrow_forward1) The amount of warfarin, used for anticoagulant medications, in a sample was calculated as follows. A 13.96 g sample was first treated with an alkaline I2 solution to convert C19H1604 to CHI3. This treatment gives one mole of CHI3 for every mole of C19H1604 that was initially present in the sample. The iodine in CHI3 is then precipitated as AgI(s) by treatment with excess AgNO3(aq): CHI3(aq) + 3AgNO3(aq) + H20(1) → 3A£I(s) + 3HNO3(aq) + CO(g) If 0.1386 g solid AgI were obtained, then what is the percentage by mass of warfarin in the sample analyzed?arrow_forward
- Define the following phenomena with reference to main group compounds: (c) dependence of acidity and basicity on oxidation statearrow_forwardGive the oxidation state of the metal for each of the following oxides of the first transition series. (Hint: Oxides of formula M3O4 are examples of mixed valence compounds in which the metal ion is present in more than oneoxidation state. It is possible to write these compound formulas in the equivalent format MO∙M2O3, to permit estimation of the metal’s two oxidation states.)(a) Sc2O3(b) TiO2(c) V2O5(d) CrO3(e) MnO2(f) Fe3O4(g) Co3O4(h) NiO(i) Cu2Oarrow_forwardExplain the following observations giving appropriate reasons: (i) The stability of +5 oxidation state decreases down the group in group 15 of the periodic table. (ii) Solid phosphorus pentachloride behaves as an ionic compound. (iii) Halogens are strong oxidizing agents.arrow_forward
- What generalizations can makeout of this lesson of electrochemistry?arrow_forwardComplete the equation for the reaction of NaHCO3(s) with HC2H3O2(aq). Include phase symbols.arrow_forwarda) Which ion, Pt(II) or Mn(II), is more likely to form a sulfide in the presence of H2S in water. b) Rationalize your answer with the trends in hard and soft character. c) Give a balance chemical equation from your reaction.arrow_forward
- Which is the least reactive alkali metal? Why is this not expected based on standard oxidation potentials? Explain why.arrow_forwardg) Taking the periodic table as a whole, discuss the trends in atomic radii evident in the table. Include in your answer a discussion on how one could use the identified trends to predict relevant reactivity of the elements towards (a) oxidation and (b) reductionarrow_forwardMetal oxides tend to be basic and react with acids True or False?arrow_forward
