The chemical common sense in the life

Food reservation: To avoid food be affected with damp be affected with damp, decay or be out of shape, often fill carbon dioxide inside doggie bag or nitrogen; or desiccative puts inside bag: Calcium of calx, chloridize is principal it is bibulous, if iron head is absorbed oxygen and water; or adopt vacuum-packed.
Rain is clear the day after tomorrow: Summer thunderstorm in the future, everybody can feel air is fresh all the more, because be when lightning,be, broke out chemical change, some oxygen in air became ozone. Thick ozone is very smelly, have very strong oxidation ability, can blanch with sterilization. Thin ozone can give a person with fresh feeling. After thunderstorm, there can be the ozone of a few in air, consequently everybody can feel air is fresh.
Old wine is sweeter: The first part of liquor is alcohol, bury wine in underground, reservation is good, after placing a few years, alcohol is mixed the show effect of less component second acid in liquor is chemical and resonant, ester of generated second acerbity second has fruit sweet smell. Although afore-mentioned echo are reversible echo, resonant rate is slower, but time is longer, also ester of more second acerbity second is generated, consequently wine jumps over Chen Yue sweet.
The 2 oxidation sulfur in food: 2 oxidation sulfur is a very first member in inorganic chemistry antiseptic, it is applied in food widely, if make the; fuming sulfur when fruit doing, preserved fruit make,become delay of 2 oxidation sulfur commentate agent, last with what wait for unripe fruit at the grape the deposit. 2 oxidation sulfur can show a variety of skill results in food, call it bleacher normally, can undertake blanching to food with coloured material effect because of 2 oxidation sulfur. On the other hand 2 oxidation sulfur has reductive effect, can restrain the active with enzymatic oxidation, restrain next enzymatic sex brown changes. Classics is long poisonous rational delibrate, everybody thinks: Sulfite preparation is in at that time applying is not to have those who showing a harm to most person below dosage. Returning those who a bit ought to clarify is: The sulfite in food is necessary to achieve regular dose, ability can bring about allergy, even if very acute sulfite is allergic person, also not be useful to place sulfite treated food all allergic, tell from this, 2 oxidation sulfur is a kind of relatively safe antiseptic.
Of washing powder choose: The washing powder that contain phosphor is to point to a kind of product that is principal auxiliary with phosphate, phosphor is element of a kind of nutrition, easy make environmental water system eutrophication, damage next water quality, pollute an environment. The washing powder that do not have phosphor is need not a kind of washing powder that phosphate makes auxiliary, this kind of washing powder does not have water quality eutrophication this one blemish, be helpful for water annulus condition protecting.
Decorate the formaldehyde that material guesses: Formaldehyde is colorless, the influence sex gas that has intense taste. Formaldehyde is former oar poison, can contact with protein, after formaldehyde of inspiratory high concentration, the severe impact that can present respiratory tract and oedema, eye is prickled, have a headache, also can break out bronchus is asthmatic. Normally formaldehyde can overspend in new illuminative house, want to put on 9 bracketplant in bridal chamber only, formaldehyde can be absorbed by some.
Toxic: Carbon monoxide (light gas to did not burn adequately) , one oxidation nitrogen
Greenhouse effect: Call greenhouse effect again, principal carbon dioxide is formed.
Acid rain (PH is worth under the pluvial) of 5.6: Coal oil natural gas can produce 2 oxidation nitrogen and azotic oxide to make acid rain in sky.
Ozonosphere: Be apart from area of ground 15-35 kilometer to be in the of 90% ozone in centering atmosphere, this one area calls advection layer ozonosphere, the freon attaint ozonosphere of freezer
