Question

What is the product obtained when \[MnS{O_4}\] solution is boiled with $Pb{O_2}$ and concentrated \[HN{O_3}\]?
A. $HMn{O_4}$
B. $Mn{O_2}$
C. $M{n_3}{O_4}$
D. $PbMn{O_4}$

Answer 1

Hint: A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.

Complete answer:
Reactants or reagents are the chemicals (or substances) that are initially involved in a chemical reaction. Chemical reactions generally involve a chemical change and the formation of one or more products with characteristics distinct from the reactants. The information on the specific path of action is part of the reaction mechanism, which frequently consists of a succession of discrete sub-steps, referred to as elementary reactions. Chemical reactions are represented symbolically by chemical equations, which show the beginning ingredients, end products, and occasionally intermediate products, as well as the reaction circumstances.
$HMn{O_4}$ is the product obtained when \[MnS{O_4}\] solution is boiled with $Pb{O_2}$ and concentrated \[HN{O_3}\]
\[2\;MnS{O_4}\; + \;5\;Pb{O_2}\; + \;6\;HN{O_3}\; \to \;2\;HMn{O_4}\; + \;2\;PbS{O_4}\; + \;3\;Pb{(N{O_3})_2}\; + \;2\;{H_2}O\]
A reaction can be classed as redox if it involves oxidation and reduction, or nonredox if it does not include oxidation and reduction. Combination, decomposition, and single displacement reactions are the most common types of redox reactions. During chemical synthesis, several chemical processes are employed to produce the desired product. In biochemistry, metabolic pathways are formed by a succession of chemical processes in which the result of one reaction is the reactant of the following reaction. Protein enzymes are often used to catalyse these processes.

So, the correct answer is “Option A”.

Note:
The inorganic compound permanganic acid (or manganic(VII) acid) has the formula $HMn{O_4}$. The dihydrate of this powerful oxoacid has been isolated. It's the permanganate salts' conjugate acid. It has been the topic of few publications, and both its characterisation and applications are restricted.
