Use the latimer diagram to solve Question 1 and 2.  

en 1. Using the following Latimer diagram (acidic conditions), what is the potential of the missing value the "?")? Answer: -0.93 0.38 -0.50 -0.51 -0.06 H₂PO HP H₂PO H₂po, PH₂ -0.28 -0.50 2. Based on the same diagram, will H3PO, disproportionate? Answer: 4. In each of the following reactions, which species is the reducing agent? a. 2 Li + Zn(NO3)2 → 2 LINO: + Zn Answer: b. 2 Na2O → 4 Na + O2 Answer: C. SnCl2 + 2 FeCl → SnCl. +2 FeCl2 Answer: 5. When KF(s) is decomposed, which element will form at the anode? Answer: 6 Bubbling chlorine gas into colorless potassium bromide solution produces a dark red solution. What is being reduced? Answer:

Answer 1

to Jaz +4 -0.93 0.32 - 3 -OSO +1 -0.51 -0.06-3 3 Hapo, > H3 P02- >p → PH, 26 go SG, = -nf bio = +0.93 F 4G2 =-MFEL = -0.38 F 163 =- FE= -2F(-0.50) = +1.0F E OGG = 86, + 8G2 +0G3 -NFE=0.93F-0.38F+ 1F -47 EU = 1.55F E--1-55--039 Ans) 20 yes H3PO, will disproportionate to PH₂ and H₃PO3 3H30 PMg + 2 H2 Blog
