Complete the reaction Zn + H2SO4=?
The chemical element zinc, which belongs to the d-group block 12, is denoted by the symbol Zn in chemical notation. The chemical formula for sulphuric acid is H2SO4 (which is considered a strong acid). Therefore, the reaction described above involves an acid reacting with metal, and the end result will be the formation of a salt and the development of hydrogen gas (H2) as a byproduct.
The equation is as follows: Zn + H2SO4 equals?
Sulfuric acid has the formula H2SO4, while zinc metal has the symbol “Zn.” Zinc is a member of group 12 of the d-block elements, and the formula for sulphuric acid is H2SO4.
Therefore, a sort of reaction known as a single displacement reaction takes place when zinc metal and sulfuric acid react with one another. In this kind of reaction, a metal or element that is more powerful (more reactive in terms of reactivity series) than the others in its compound pushes the other elements out of the complex.
The reactivity of elements is described by the reactivity series, in which the order of the reactivity of metals, decreasing from most reactive to least reactive, is as follows:
K>Na>Ca>Mg>Al>Zn>Fe>Pb>H>Cu>Hg>Ag>Au
Since Zinc metal is much more reactive than Hydrogen, it is able to easily displace hydrogen from H2SO4 and it forms a salt ZnSO4. The hydrogen that was displaced will be released (evolved) in the form of hydrogen gas (H2) as a result of this reaction. We can see clearly that Zinc metal is significantly more reactive than Hydrogen.
Therefore, it is possible to draw the conclusion that a reaction between a metal and an acid would result in the formation of two products, namely salt and hydrogen gas (H2).
As a result, the comprehensive reaction will proceed as follows:
Zn + H2SO4 → ZnSO4 + H2
Producing hydrogen gas from this reaction is a common practice in many scientific research facilities.
