Question

3.74. (a) Write the formula of the oxo anions likely to be formed by the following elements with the oxidation states shown in parentheses:F (III); B (V); Br(III); Si(IV) C(IV) S(IV) (b) Calculate the pK, for each formula you have written. (c) Classify the basicity of each anion (weakly basic, etc.)

Answer 1

A) Phosphite (PO_3^3-) is the oxoanion of P(III)

Br(III) : Bromite(BrO₂^-) is the oxoanion

Br(v) : Bromate( BrO_3^-) is the oxoanion

Si(IV) : Silicate(SiO_{3^{2-) is the oxoanion}}

  C(IV) : Carbonate ( CO_3^2-) is the oxoanion

S(IV) : Sulfur (SO_3^2-)  is the oxoanion
