Q:Common inorganic salt ions will appear when the corresponding symptoms
Iron ion: iron deficiency anemia
Q:Is calcium carbide inactive?
Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
Q:how come inorganic salts increase surface tension of water?
It okorder.com/
Q:Fitness body side, the body protein exceeded, inorganic salt normal, how can I do?
Strengthen exercise consumption.
Q:Which foods contain calcium-containing inorganic salts
Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of minerals: 1. constitute the body of the material. (Such as calcium, phosphorus, magnesium is a bone, an important component of the teeth.) 2. Regulate the physiological function. (Minerals are often enzymes activators.) 3. Participate in the regulation of body fluid balance and maintain the body's acid-base balance.
Q:General identification method of inorganic salts
Take platinum wire, with hydrochloric acid wet, dipped in the test sample, burning in the colorless flame, the flame that was purple. But a small amount of sodium mixed, must be separated from the blue glass perspective can be identified. 2K ++ [PtCI6] 2- → K2PtCI6
Q:What are the nutritional requirements for bacterial growth?
For water: the nutrients required for bacteria must be dissolved in water, nutrient absorption and metabolism are required to carry out water.
Q:Does the plant absorb some of the inorganic salt?
Plants absorb moisture and absorb inorganic salts are two relatively independent processes.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
