A student wanted to test if certain LED lights will light up when attached to a silver/lithium battery. The LED lights have a forward voltage (VF) rating which is the minimum voltage needed to light the bulbs. The bulbs tested and their corresponding VF values were the following: Red = 1.8 - 2.0 V Blue = 2.9 - 3.2 V Green = 2.1 - 2.2 V White = 4.0 - 4.2 V Yellow = 2.0 -2.2 V Orange = 1.9 - 2.0 V Answer the following questions based on the galvanic cell the student has constructed. a. The standard reduction potentials for silver and lithium are: Ag* (aq) + e¯ → Ag (s) E° = 0.80 V Li* (aq) + e- → Li (s) E°=-3.04 V What is the overall Ecell for the galvanic cell made from these two reactions? b. Write out the overall balanced equation for the galvanic cell using the information in part a. What would be an appropriate electrolyte solutions for each half cell? с.
