Is K2Cr2O7 an oxidizing agent?

Potassium Dichromate Potassium dichromate, K2Cr2O7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. It is a crystalline ionic solid with a very bright, red-orange color.

What is the charge of K2Cr2O7?

+1 charge

What are the oxidation states of each element in k2cro4?

Chromium is in its hexavalent state (+6) in this compound – the 4 oxygen atoms are each -2 (total of -8) and the potassium ions are +1 each, so in order to balance the sum of the oxidation numbers (which have to be 0 for a neutral compound), the chromium has to be +6 (2+6-8=0).

Which element has most oxidation states?

Manganese

What is the difference between oxidation number method and ion electron method?

The key difference between ion electron method and oxidation number method is that in ion electron method, the reaction is balanced depending on the charge of ions whereas, in oxidation number method, the reaction is balanced depending on the change in oxidation numbers of oxidants and reductants.

What is the oxidation state range of P?

The most important oxidation numbers for phosphorus are -3, +3, and +5 (see table below). Because it is more electronegative than most metals, phosphorus reacts with metals at elevated temperatures to form phosphides, in which it has an oxidation number of -3.
