- Electrolysis of an alkaline earth metal chloride using a current of 5.00 A for 748 seconds deposits 0.471 g of metal at an electrode. Is the metal deposited at the cathode or the anode of the electrolytic cell? What is produced at the other electrode? What is the identity of the alkaline earth metal?arrow_forwardDraw Lewis structures for the AsCl4+ and AsCl6 ions. What type of reaction (acid-base, oxidation-reduction, or the like) is the following? 2AsCl5(g)AsCl4AsCl6(s)arrow_forwardWhich of the following statements is not correct?

(d) HF is used to etch glass.arrow_forward
- The photograph below shows what occurs when a solution of potassium chromate is treated with a few drops of concentrated hydrochloric acid. Some of the bright yellow chromate ion is converted to the orange dichromate ion. 2 CrO42(aq) + 2 H3O+(aq) CrO72(aq) + 3 H2O() (a) Explain this experimental observation in terms of Le Chateliers principle. (b) What would you observe if you treated the orange solution with sodium hydroxide? Explain your observation.arrow_forwardUse Table 17.1 to select (a) a reducing agent in acidic solution that converts ClO3- to Cl2 but not Cr2O72- to Cr3+. (b) an oxidizing agent that converts Mg to Mg2+ but not Mn to Mn2+. (c) a reducing agent in basic solution that converts NO2- to NO3- but not OH- to O2.arrow_forwardWhich of the following elements is most likely to be used to prepare La by the reduction of La2O3: Al, C, or Fe? Why?arrow_forward
