Chemistry Amphiprotic Species Research Paper 3-8. When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.9 ◊ 10-7 m and (b) 4.2 ◊ 10-7 m.
What are the frequencies of the two lines? What color do we see when we heat a rubidium compound?
3-76 Based on their positions in the periodic table, list the following atoms in order of increasing radius: Sr, Ca, Si, Cl.
4-11. What are amphiprotic species? Illustrate with suitable equations
4-14. Is the self-ionization of water endothermic or exothermic? The ionization constant for water (Kw) is 2.9 ◊ 10-14 at 40 ∞C and 9.3 ◊ 10-14 at 60 ∞C.
