Reggio Emilia designates the different ages of their balsamic vinegar (aceto balsamico tradizionale di Reggio Emilia) by label colour. A red label means the ...
The aluminium takes an oxygen atom from sodium hydroxide, which in turn takes an oxygen atom from water, and releases two hydrogen atoms. The reaction thus produces hydrogen gas and sodium aluminate. In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in.

The acetic acid in vinegar is what provides most of the health benefits, and all types of vinegar used for cooking contain about the same amount of acetic acid, Johnston says.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Sodium hydroxide is used in the manufacture of soap, paper, and the synthetic fiber rayon. Calcium hydroxide (slaked lime) is used in the manufacture of bleaching powder. Calcium hydroxide is also used to clean the sulfur dioxide, which is caused by the exhaust, that is found in power plants and factories. [9]
Unlike inexpensive Balsamic Vinegar of Modena (BVM), Traditional Balsamic Vinegar (TBV) is produced from cooked grape must, aged at least 12 years, and protected under the European protected designation of origin (PDO) system, fetching higher prices [1] (BVM has lesser protection under the European protected geographical indication (PGI) system ...
