Birch sap can also be used as an ingredient in food or drink recipes, [19] such as birch beer or wintergreen-flavored candy. Concentrated birch sap is used to make birch syrup , a very expensive type of syrup mainly made from paper birch in Alaska [ 20 ] and Canada, and from several species in Latvia , Russia , Belarus , and Ukraine .
In home gardens, for example, the seeds of plants which are otherwise difficult to grow from seed may be made viable through scarification. The thawing and freezing of water, fire and smoke and chemical reactions in nature are what allow seeds to germinate but the process can be sped up by using the various methods described thus far.
The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1] The carbon snake experiment can sometimes be misidentified as the black snake, "sugar snake ...
Hygroscopic substances include cellulose fibers (such as cotton and paper), sugar, caramel, honey, glycerol, ethanol, wood, methanol, sulfuric acid, many fertilizer chemicals, many salts and a wide variety of other substances. [5] If a compound dissolves in water, then it is considered to be hydrophilic. [6]
They are prepared from sulfuric acid and the alcohol. The main examples are diethyl sulfate and dimethyl sulfate, colourless liquids that are used as reagents in organic synthesis. These compounds are potentially dangerous alkylating agents. Dialkylsulfates do not occur in nature. [5]

China is the biggest supplier of furfural, and accounts for the greater part of global capacity. The other two major commercial producers are Illovo Sugar in South Africa and Central Romana in the Dominican Republic. [20] In the laboratory, furfural can be synthesized from plant material by heating with sulfuric acid [21] or other acids.
Like concentrated sulfuric acid, oleum is such a strong dehydrating agent that if poured onto powdered glucose, or virtually any other sugar, it will draw the hydrogen elements of water out of the sugar in an exothermic reaction, leaving a residue of nearly pure carbon as a solid. This carbon expands outward, hardening as a solid black ...
