Question

Zn+H2So4=ZnSo4+H2
1)write the ionic equation
2)these can be represented by two half equation. Write them
3)why is it redox reaction?

Answer 1

The given reaction is:

$\mathrm{Zn}+\mathrm{H}_{2} \mathrm{SO}_{4}=\mathrm{ZnSO}_{4}+\mathrm{H}_{2}$

a. The ionic reaction is as follows:

$\begin{array}{l}{\text { Zn (solid) }+2 \mathrm{H}^{+} \text { (aqueous) }+\mathrm{SO}_{4}^{2-}(\text { aqueous }) \Leftrightarrow \mathrm{H}_{2}(\mathrm{gas})+\mathrm{Zn}^{2+}(\text { aqueous })+} \\ {2 \mathrm{SO}_{4}^{2-} \text { (aqueous) }}\end{array}$

b. Yes it can be written in terms of two half reactions where the Cl ions are omitted and only the ions undergoing oxidation and reduction are included. These half reactions are:

$\mathrm{Zn} \Leftrightarrow \mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \text { and } 2 \mathrm{H}^{+}+2 \mathrm{e}^{-} \Leftrightarrow \mathrm{H}_{2}$

c. This reaction is a redox reaction as oxidation and reduction are taking place simultaneously. While zinc gets oxidised, hydrogen sulphate gets reduced.

Answer 2

Answer:

Here is your answer buddy

This reaction is a redox reaction as oxidation and reduction are taking place simultaneously. While zinc get oxidised.

Zn + H2SO4 → ZnSO4 + H. 2

Zn + H2SO4 → ZnSO4 + H. 2Zinc react with sulfuric acid to produce zinc sulfate and hydrogen.
