Zn is the 24^{th} most abundant element in the Earth crust, having a shiny grey appearance. Let us look at how Zn reacts with H_{2}SO_{4} with the help of this article.

**H _{2}SO_{4} reacts with Zn metal to release gas and a salt is formed. H_{2}SO_{4} is a commonly used dehydrating agent of organic chemistry. It is also used to provide an acidic medium to the reaction. Zn is a brittle metal found in the Earth crust. Zinc atomic number is 30 and it is the first element of group 12.**

**Is ****H**_{2}SO_{4} + Zn a buffer solution

**H**a buffer solution

_{2}SO_{4}+ Zn**H _{2}SO_{4} + Zn reaction is not a buffer solution because H_{2}SO_{4} used here is a strong acid, but for a buffer solution, there must be a weak acid available.**
