Sulphuric acid is a strong inorganic acid, which can be mixed with water in any ratio. It also has strong water absorbing properties, and it is one of the most important products of the chemical industry. One should be very careful with this acid as it is very corrosive. It is used in the production of mineral fertilizers, in oil refinement processes, in ore and waste water treatment, in various kinds of accumulators, in vulcanization processes, and in the chemical industry for the production of many substances (medications, paints, pigments, soaps, detergents, explosives, plastic materials, etc.).

Concentrated sulphuric acid can be ordered in drugstores/pharmacies, at a relatively high price (min. 15€ per liter). It can also be bought from companies that sell chemicals, at a lower price, but only if one orders larger amounts. Lower concentrated solutions can be obtained at a much lower price, or even for free, at workshops that repair and sell car accumulators. We also heard that it can be bought in stores that sell plumbing equipment, but we didn't check. The price: 7 to 20€ per liter, depending on purity and place it is ordered from.
