Interpretation:
The oxidation states of all the atoms in CrCl3 should be determined.
Concept Introduction:
The oxidation state is defined as the charge(s) that an atom would have when electron(s) were transferred completely from a molecule or ion.
Interpretation:
The oxidation states of all the atoms in K2 CrO4 should be determined.
Concept Introduction:
The oxidation state is defined as the charge(s) that an atom would have when electron(s) were transferred completely from a molecule or ion.

- An aqueous solution of an unknown salt of vanadium is electrolyzed by a current of 2.50 amps for 1.90 hours. The electroplating is carried out with an efficiency of 95.0%, resulting in a deposit of 2.850 g of vanadium. a How many faradays are required to deposit the vanadium? b What is the charge on the vanadium ions (based on your calculations)?arrow_forwardPredict the products of the following reactions and balance the equations. (a) Zn is added to a solution of Cr2(SO4)3 in acid. (b) FeCl2 is added to a solution containing an excess of Cr2O72- in hydrochloric acid. (c) Cr2+ is added to Cr2O72- in acid solution. (d) Mn is heated with CrO3. (e) CrO is added to 2HNO3 in water. (f) FeCl3 is added to an aqueous solution of NaOH.arrow_forwardConsider the reducing agents Cu+(aq), Zn(s), and Fe(s).
