Both salt, and sugar represent firm transparent crystals with bright taste. However these two products only externally are similar. Salt — substance mineral, and sugar — organic.
The chemical formula of sugar looks as C12H22O11, salts — NaCl. Sugar is a product of processing of sugar beet or reed, salt is usually extracted in the mine way.
Whether sugar smells
Can catch a smell of people only from those substances which in a usual state are flying and unstable. Sugar can decay and be split only at 186 °C. That is at the room temperature this product smells of nothing at all.
Sometimes any smells from granulated sugar can proceed nevertheless. But occurs just in case houses or such product was stored in a warehouse near something silnopakhnushchy or deteriorated. Being excellent absorbent, sugar very easily absorbs any foreign smells.
Sugar can sometimes smell also of sugar beet. So occurs when this product in the course of production is insufficiently well cleaned from a press.
Whether salt has a smell
No substances capable to exude smells also are a part of table salt. That is in pure form and under normal conditions such crystals do not smell of anything.
However, as well as sugar, salt belongs to group of strong absorbents. Therefore from it various foreign smells of organic chemistry or any other substances also in certain cases can proceed.
To make salt more useful to a human body, by production often add iodine to it. This substance is flying and the smell has specific, strong and sharp. Therefore iodinated salt always smells of iodine a little.
Differences between salt and sugar
Both of these products, thus, in pure form have no smell. Externally they are really very similar, however salt crystals, in comparison with sugar crystals, nevertheless differ in a little more dark color. Besides, and they usually have the sizes more.
Sugar, unlike salt, is substance combustible. In the form of dust it can even be explosive. Particles of icing sugar have the sizes in only 0.1 mm and very quickly are oxidized. Such motes amicably and almost in one stage burn down. Therefore process of their burning as explosion of rather big power looks.
Different properties have also water solutions of these two popular products. The difficult molecule of sugar at its dissolution does not decay. NaCl in water breaks up to negatively and positively charged ions of chlorine and sodium. Therefore salt solutions very well carry electric current. Solutions of sugar of such ability are deprived.
