Auto Reduction

What is the auto oxidation -reduction half -reactions ? Explain it with a suitable example.

Which of the following oxides cannot be reduced by auto or self reduction ?

Which of the following oxides cannot be reduced by auto or self reduction ?

Which of the following undergoes an auto (self) reduction ? i) PbO ii) Fe_2O_3 iii) Cu_2S iv) TiCl_4

The heating process for the extraction of elements are quite old but highly acceptable method for the extraction of elements. Become in this process the elements produced is in the highly pure state. Mostly As, Sb,Ni, Zr,B etc are prepared by this principle 4 mumber of metal sulphides which may be reated first in air to partially convert them to the aride, and then further roasted in the absence of air, wing self reduction. For which of the given sulphides auto reduction is applicable

An element A occupies group number 15 and period number 3, reacts with chlorine to give compound B. The compound Bon hydrolysis gives a dibasic acidC. The compound C on heating undergoes auto oxidation and reduction to give a tribasic acid D. Identify the element A, compound B,C and D. Write the reactions.
