2010年高考化学试题分类汇编——电化学基础（国外英文资料） The classification of the chemistry exam of the 2010 college entrance exam is compiled Electrochemical based (1) the image of a dye-sensitized solar cell is shown in the right image. A point is extremely by organic photosensitive fuel cell (S) coated on the surface of nanocrystalline, another electrode consists of conductive glass platinum plating, in the cells of the reaction: (excited) The following statement about the battery is incorrect: A: when youre working on A battery, youre converting solar energy into electricity When the battery is working, the ions discharge on the plate-plated conductive glass electrode C. The platinizing conductive glass in the battery is positive D. the concentration of I - and I3 - in the electrolyte solution of the battery will not decrease Option B error parsing 】 【 from sketch to see in the open circuit in electronic from negative to positive, also to do the positive plating platinum electrode and reduction reaction: I3 - + 2 = 3 I - e; A option right, this is A solar cell, as you can see device schematic is A galvanic cell, is ultimately convert light energy into chemical energy, should add up the above four reaction, chemical does not reduce; C is correct. D is correct, the total essential part of the solar cells is: I3-3 I - conversion (and I2 + I - I3 -), the other part is photosensitive reciprocal transformation of organic matter from the excited state and ground state, all the chemicals are not eventually be loss! The answer B Examination proposition intention 】 【 new battery, battery two electrode reaction, the electronic flow and current direction, the working principle of solar cells, battery, such as total reactive also examines the examinee to flexible ability and psychological quality, can adapt to unfamiliar situations apply their knowledge to solve new problems Comments 】 【 subject conception is very good, but check for thin, and materials is not the latest, yancheng city, jiangsu prov
