What is the formula for selenic acid?

Write a formula for each acid.
a) Phosphoric acid b) hydrobromic acid c) Sulfurous acid.

While selenic acid has the formula H2SeO4 and thus is directly related to sulfuric acid, telluric acid is best visualized as H6TeO6 or Te(OH)6?

  1. What is the oxidation state of tellurium in Te(OH)6?
  2. Despite its structural differences with sulfuric and selenic acid, telluric acid is a diprotic acid with pKa1 = 7.68 and pKa2 = 11.29 Telluric add can be prepared by hydrolysis of tellurium hexafluoride according to the equation;

TeF6 (g) + 6H2O (l) β†’ Te(OH)6 (aq) + 6HF (aq)

Tellurium hexafluoride can be prepared by the reaction of elemental tellurium with fluorine gas:

Te (s) + 3F2 (g) β†’ TeF6 (g)

If a cubic block of tellurium (density = 6.240 g/cm3) measuring 0.545 cm on edge is allowed to react with 2.34 L fluorine gas at 1.06atm and 25Β°C, what is the pH of a solution of Te(OH)6 formed by dissolving the isolated TeF6 (g) in 115 mL solution? Assume 100% yield in all reactions.
