One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light. The steel is dissolved in nitric acid, producing the manganese(II) ion and nitrogen dioxide gas. This solution is then reacted with an acidic solution containing periodate ion; the products are the permanganate and iodate ions. Write balanced chemical equations for both these steps.
Why fluids are important in chemical engineering - enormous number of materials normally exist as gases or liquids, or can be transformed into such phase and explain systematic description of change in fluid systems, mechanical change
