Q:What does salt form when it dissolves?

Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.

Q:What are the effects of inorganic salts on plant growth?

K: make the stem robust, promote starch formation. Lack of performance: stems weak, easy to lodging, leaves the edge and the tip was brown, and gradually dry.

Q:What are minerals and trace elements?

Trace elements refers to the body weight of one thousandth of the body weight, daily requirements are generally in the following 0.01 grams can meet the physiological needs of the human body, as we often talk about iron, zinc, iodine, selenium, fluoride and so on. Calcium in the human body due to more content, the daily requirements of several hundred milligrams, it is a macro element.

Q:What is the inorganic salt, is not the organic salt and is not the inorganic salt

There is no concept of organic salt inorganic salt inorganic salts in the class of chanting

Q:What are the important physiological functions of inorganic salts in cells

Maintain the living activities of the organism. Such as: magnesium ions are ATPase activator, chloride ion is an activator of saliva enzyme.

Q:What is the acid egg

1 vinegar egg preparation to take fresh eggs 10, 9 degrees vinegar (or local quality vinegar) 500ml, honey or sugar amount. With alcohol disinfection of eggs into the porcelain containers, and then into the vinegar, sealed 48 hours, until the eggshell softened, only thin egg wrapped in swollen eggs, unsealed, the egg skin smashed, the egg white, Egg yolk and vinegar mix, then placed after 24 hours available. 2 use method to take vinegar egg 40 ~ 50ml, plus 2 to 3 times the warm water, plus the right amount of honey or sugar, feeding a day, once every 10 to 15 days can be. 3 cases on March 5, 1999, a farmer 1 pig susceptible treatment. Symptoms: normal body temperature, loss of appetite, defecation difficulties, often for defecation posture, sometimes discharged dry and small dung ball, and with white or red brown mucus, urine deep yellow and small, palpable abdominal touch To the large intestine with dry hard feces, diagnosed as constipation. Then with rhubarb 100g, fruit guide 10 feeding service, intramuscular injection VB1 10ml, once every 3 days, although the constipation has been alleviated, but a week later, the symptoms as early as possible. Second consultation in the original drug on the basis of plus Ma Ren 12g, talc, rhubarb, Yuan Mingfen, Citrus aurantium 9g, Jianshui feeding service, once every 3 days, still ineffective. Finally diagnosed as habitual constipation, then the law of the use of vinegar egg treatment for 10 days, told more, no recurrence. 4 experience vinegar egg drawn easy, affordable, effective, can be widely used in habitual constipation, constipation caused by infectious diseases, antibiotics should be based on the treatment, with the application of vinegar egg, the effect will be more satisfied.

Q:During the different periods of plant growth, the amount of water and inorganic salt required is different.

Plant life, although the need for a variety of inorganic salts, but different plants on the various types of inorganic salt requirements are different, such as cabbage, spinach and other human needs leaves of vegetables need nitrogen containing inorganic salts, tomato, peanuts need phosphorus Of the inorganic salt and more, sweet potatoes, potatoes need potassium-containing inorganic salts; the same plant with the growth period of the different requirements of inorganic salts are not the same, for example, plants in the seedling period requires nitrogenous inorganic salts , In the flowering, the results of the period of time need more phosphorus-containing inorganic salts. Therefore, different plants and the same plant growth period, the need for inorganic salts are different. So the answer is: different; different

Q:Is SiO2 an amphoteric oxide?

Not though SiO2 reacts with HF but the reason for this reaction is not because H + is because Si and F-coordination generated SiF4 is very stable.

Q:For example, sulfates can emit SO2 or SO3 gas. If this were to occur in this experiment, would the % H2O calculated from the data be too high or too low? Explain.

You would measure the mass lost, and you would assume that this is equal to the amount of water that was in the sample. So decomposition would add to the mass lost during heating and this would lead you to overestimate the amount of water that was in the sample, and overestimate the %h20.

Q:The lack of symptoms and food sources of several inorganic salts

Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
