Choose the one alternative that best completes the statement or answers the question The gain of electrons by an element is called __________ oxidation sublimation reduction disproportionation fractionation __________ is reduced in the following reaction: Cr2O72- + 6S2O32- + 14H+ ¬ 2Cr3+ + 3S4O62- + 7H2O |
What is EMF in a redox reaction?
The emf can be thought of as being a measure of the driving force for a redox process. In an electrolytic cell an external source of energy is required to force the reaction to proceed. In order to drive the nonspontaneous reaction, the external emf must be greater than Ecell. 2) __________ is the oxidizing agent in the reaction below.
What are oxidation-reduction reactions?
called oxidation-reduction reactions (redox reactions). Oxidation involves loss of electrons (OIL). Reduction involves gain of electrons (RIG). Electrochemistry deals with relationships between electricity and chemical reactions. The oxidation numbers of Zn and H+ have changed. The ox# of Zn has increased from 0 to +2.
What is the difference between oxidation and reduction in chemistry?
Oxidation involves loss of electrons (OIL). Reduction involves gain of electrons (RIG). Electrochemistry deals with relationships between electricity and chemical reactions. The oxidation numbers of Zn and H+ have changed. The ox# of Zn has increased from 0 to +2. The ox# of H has decreased from +1 to 0.
