A Copper-Zinc battery – What Matters
{"Image DocumentName": "A Copper-Zinc battery \u2013 What Matters?", "Image ImageDescription": "Consider reduction potentials: Cu+2 + 2e- \u2192 Cu(s) V. Zn+2 + 2e- \u2192 Zn(s) V. Place Zn electrode in copper sulfate solution \u2013 What happens? Copper is plated on Zn electrode. Cu+2 + 2e- \u2192 Cu(s) V. Zn(s) \u2192 Zn+2 + 2e V. E > 0, spontaneous. Cu+2 + Zn(s) \u2192 Zn+2 + Cu(s) 1.1 V. Note, no need for electron to flow external to cell for reaction to occur!!", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
