化学与人们生活息息相关,从日常生活中可以积累很多的化学知识.这样,就可以加深对所学知识的理解,从而提高对化学的学习兴趣.
食盐味咸,常用来调味,或腌制鱼肉、蛋和蔬菜等,是一种用量最多、最广的调味品,素称“百味之王”.人们每天都要吃一定量的盐(一般成年人每天吃6g到15g食盐就足够了),其原因一是增加口味,二则是人体机能的需要.Na+主要存在于细胞外液,是维持细胞外液渗透压和容量的重要成分.动物血液中盐浓度是恒定的,盐分的过多流失或补充不够就会增大兴奋性,于是发生无力和颤抖,最后导致动物后腿麻痹,直至死亡.美国科学家泰勒亲身体会了吃无盐食物的过程,起初是出汗增加,食欲消失,5天后感到十分疲惫,到第8~9天则感到肌肉疼痛和僵硬,继而发生失眠和肌肉抽搐,后因情况更为严重而被迫终止实验.当然,摄取过多的食盐,就会把水分从细胞中吸收回体液中,使机体因缺水而发烧.
把空气中的氮气转化为可被植物吸收的氮的化合物的过程,称为氮的固定.自然界中氮的固定通常有两种:一种是闪电时空气中的氮气和氧气化合物生一氧化氮,一氧化氮进一步与氧气化合生成二氧化氮,二氧化氮被水吸收变成硝酸在下雨时降落到地面.另一种固氮的方式是利用植物的根瘤菌,根瘤菌是一种细菌,能使豆科植物的根部形成根瘤,在自然条件下,它能把空气中的氮气转化为含氮的化合物,供植物利用.“种豆子不上肥,连种几年地更肥”就是讲的这个道理.
松花皮蛋是我国人民的传统食品.由于它风味独特、口感极好、保质期长,很受人们喜爱.同学们知道吗?其实,将鲜蛋加工成松花皮蛋的过程是一种比较复杂的化学过程.灰料中的强碱(氢氧化钠、氢氧化钾)从蛋壳外渗透到蛋黄和蛋清中,与其中的蛋白质作用,致使蛋白质分解、凝固并放出少量的硫化氢气体.同时,渗入的碱进一步与蛋白质分解出的氨基酸发生中和反应,生成的盐的晶体以漂亮的外形凝结在蛋清中,像一朵一朵的“松花”.而硫化氢气体则与蛋黄和蛋清中的矿物质作用生成各种硫化物,于是蛋黄、蛋清的颜色发生变化,蛋黄呈墨绿色,蛋清呈特殊的茶绿色.食盐可使皮蛋收缩离壳,增加口感和防腐等.加入的铅丹可催熟皮蛋,促使皮蛋收缩离壳.而茶叶中的单宁和芳香油,可使蛋白质凝固着色和增加皮蛋的风味.

蜜蜂是完全以花(包括花粉和花蜜)为食的昆虫,在蜜源丰富的季节蜜蜂会将花蜜酿成蜂蜜储存起来,
蚂蚁大多都是杂食性昆虫,主要以植物种子及昆虫尸体为食且和蜜蜂一样有储备食物的习性。
三、营巢方式不同
蜜蜂的筑巢材料是工蜂分泌的蜂蜡,蜂蜡筑成巢房并紧密排列成巢脾,整个非常则由数张或十数张巢脾组成,
蚂蚁大多数种类掘土筑巢于地下或腐烂的树干中。
在蚁群中一般只有分工而没有等级,蚁后的待遇和其他蚂蚁没有区别,
蜂群中的等级制度非常明显且严格,蜂王的待遇尤其是在食物上要远远优于其他蜜蜂

Salt flavour is salty, commonly used will flavor, or souse cruelly oppress, egg and vegetable, it is the dressing with a kind of the most, widest dosage, element says " the king of 100 flavour " . The salt that people wants to take certain amount everyday (general adult eats 6g to arrive everyday 15g salt is enough) , its reason is to add taste, it is the outside needing cell of.Na+ main consist in fluid of human performance second, it is to maintain the fluid outside the cell to permeate control the important part with the capacity. Chroma of the salt in animal blood is constant, the overmuch prediction of a person's luck in a given year of salinity or complement can increase not quite stimulant, happen to be mixed feebly then asp, bring about animal hind leg finally paralytic, till die. Taylor experienced American scientist to take course of the alimental that do not have salt personally, it is to perspire at first increase, appetite disappears, feel very tired out after 5 days, to the 8th ~ 9 days feel muscle is mixed sorely inflexible, then produces insomnia and jerk, hind because the case is more severe and be forced to stop a test. Of course, absorb overmuch salt, can absorb moisture from inside the cell time humoral in, make airframe has a fever because of lacking water.
the process of the compound of the nitrogen that the nitrogen translate into in air can be absorbed by the plant, those who call nitrogen is fixed. Of the nitrogen in nature fixed have two kinds normally: One kind is the air when lightning medium nitrogen and aerobic compound give birth to one oxidation nitrogen, one oxidation nitrogen generates 2 oxidation nitrogen with aerobic chemical combination further, 2 oxidation nitrogen is absorbed to become nitric acid to descend to the ground when rain by water. The means of nitrogen of another kind of solid is to use floral rhizobium, rhizobium is a kind of bacterium, can make root ministry forms leguminous floral root nodule, below natural condition, it can the compound of nitric of nitrogen translate into in air, use for the plant. "Kind bean do not go up fat, plant repeatedly a few years of ground are more fertile " this truth that tells namely.
Egg of preserved egg skin is the traditional food of our country people. As a result of its gust wonderful, expiration period grows distinctive, mouthfeel, very suffer people to love. Do classmates know? Actually, the process that processes bright egg egg of preserved egg skin is a kind of more complex chemical process. The alkali in grey makings (hydrogenous oxidation natrium, oxyhydrogen changes potassium) from inside yoke and egg white are permeated outside chorion, with among them protein action, cause protein to decompose, caky give off a few vulcanization hydrogen gas. In the meantime, of infiltration alkaline decompose those who go out is amino acerbity happening to counteract reaction with protein further, the crystal of generated salt condenses in egg white with beautiful shell, resemble " preserved egg " . And the mineral action in enraging body criterion and yoke and egg white generates vulcanization hydrogen all sorts of sulfide, then the color of yoke, egg white produces change, yoke shows blackish green scene, egg white shows special tea green. Salt can make leather egg systole leaves case, increase mouthfeel and anticorrosive etc. Affiliation read lead but egg of skin of accelerate the ripening, make leather egg systole leave case. And the Chan Ning in tea and balmy oil, can make protein caky and chromatic with the special flavor that adds leather egg.
