Question

Is Vinegar Corrosive to Metal?

Answer 1

Vinegar has an acidic nature, prolonged exposure to aluminum can corrode the metal.

Corrosion: The process through which pure metals turn into unwanted compounds when exposed to elements such as water or air.

1. The metal is damaged and decomposed as a result of this reaction, starting with the area that is exposed to the environment and eventually affecting the total mass of the metal.
2. It is common practice to use the Deal-Grove model to explain how the oxide layer is formed.
3. forced different situations, this model aids in forecasting and managing the production of oxide layers.
4. Corrosion can also be measured using a weight reduction approach. In this process, a fresh, precisely weighed piece of metal or alloy is exposed to a corrosive environment for a predetermined amount of time.
5. After that, the rust products are removed through cleaning.
6. Mannings of corrosion (R) describe

$\mathrm{R}=\frac{\mathrm{\kappa W}}{\mathrm{\rho At}}$

$$\begin{gathered} \mathrm{Where},\mathrm{k}=\mathrm{constant}, \\ \mathrm{W}=\mathrm{weight}\mathrm{loss}\mathrm{of}\mathrm{the}\mathrm{metal}\mathrm{in}\mathrm{time}\mathrm{t}, \\ \mathrm{A}=\mathrm{surface}\mathrm{area}\mathrm{of}\mathrm{the}\mathrm{metal}\mathrm{exposed}, \\ \mathrm{\rho }\mathrm{is}\mathrm{the}\mathrm{density}\mathrm{of}\mathrm{the}\mathrm{metal}(\mathrm{in}\mathrm{g}/\mathrm{cm}³). \end{gathered}$$

Silver Tarnishing is an example of Corrosion: Sulfur compounds in the air react with silver to form silver sulfide (${\mathbf{Ag}}_{\mathbf{2}}\mathbf{S}$), which is black, As exposed silver combines with atmospheric ${\mathbf{H}}_{\mathbf{2}}\mathbf{S}$(g), which is present as a result of some industrial operations, ${\mathbf{Ag}}_{\mathbf{2}}\mathbf{S}$ is created.

$2\mathrm{Ag}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)\to {\mathrm{Ag}}_2\mathrm{S}\left(\mathrm{s}\right)+2{\mathrm{H}}^{+}\left(\mathrm{g}\right)$

Hence, Vinegar is Corrosive To Metal.
