The ion HTe- is an amphiprotic species; it can act as either an acid or a base. (a) What is K_mathrma for the acid reaction of HTe- with H₂O? (b) What is K_b for the reaction in which HTe- functions as a base in water? (c) Demonstrate whether or not the second ionization of H_2 Te can be neglected in the calculation of [HTe-] in a 0.10 M solution of H_2 Te?
