1.	Hydrogen is a common reductantof organic chemicals, but it isnotwidelyused in metallurgy. Substantiate.
Answer» Solution :METALLURGICAL reductions are usually high temperature processes. At elivated temperatures, hydrogen may form hydrides withmetals. Metallurgical OPERATIONS in open VESSELS lead to be combination of hydrogen with oxygento form water. Further, Ellinghamcurve has a positive slopeand is parallel to the CURVES of several metal OXIDES.
