Chemical products are ubiquitous in daily life and widely used. Examples are as follows: Salt tastes salty, and is often used to flavor or preserve fish, eggs and vegetables. It is a condiment with the largest amount and the widest range, and is known as the "King of 100 flavors".People need to eat a certain amount of salt every day (the average adult eats between 6 and 15 grams of salt a day), both for taste and for functional reasons.Na+ mainly exists in extracellular fluid and is an important component to maintain the osmotic pressure and volume of extracellular fluid.The salt concentration in the animal's blood is constant, and too much loss of salt or not enough of it increases excitability, leading to weakness and trembling, which leads to paralysis of the hind legs until death.Of course, ingesting too much salt will absorb water from the cells back into body fluids, causing the body to have a fever due to lack of water.Green chemistry is mainly used to improve some highly polluting reactions in chemical production, or some new technology to make a reaction that would otherwise be achieved through several processes in one step.Still have is to use current membrane to separate technology to separate a few harmful material, for instance use membrane to separate technology to separate carbon dioxide to wait.Then there is the use of green fuels to make them burn more efficiently.Sodium benzoate has the function of sterilization and inhibiting the growth of bacteria, widely used in food, medicine, cosmetics, toothpaste, spices, tobacco and feed preservatives, can also be used in the car cooling system rust prevention, packaging pulp, latex paint, cutting oil and machine to prevent metal corrosion, as a plastic additive.
Someone put chemical called a "magic wand" in modern society, it can from the ore smelting iron and steel, will bark, wood chips into fiber, can make the black oil into the colorful cloth, can grow "wool", make the coal can be waste things that are good for you, for all kinds of food to the survival of humans, eternal youth cosmetics and conquer disease, prolong life of the "panacea"...People's life "everywhere has chemistry, everywhere has chemistry".All kinds of activities of human life, such as clothing, food, shelter, transportation, use, study and play, are inseparable from chemistry.Highly developed chemical products have enriched the life of modern people.
