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:Can inorganic salts act as stabilizers for emulsified asphalt?
Heze Tongren Road Machinery Co., Ltd. is a asphalt heating and storage equipment as the main body, set road maintenance equipment production, asphalt library design and transformation of technical services, to undertake asphalt library / depot and other construction and installation, industrial pipelines and chemical equipment The installation of the installation of the boiler, the installation of steel structures and accessories sales, such as integrated services in one company.
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:Why are inorganic sodium salts much better soluble in ethanol than potassium salts?
The reason seems to be : - Ionization potential of pottasium is lower than that of sodium ,thereore potassium salts are more polar as compared to sodium salts; - Potassium being more reactive than the sodium reacts faster withbwater,
Q:Chemical formula The longest inorganic salt
Basic copper carbonate Cu2 (OH) 2CO3
Q:What does salt form when it dissolves?
ions. depending on which kind of salt: NaCl -> Na+ + Cl-
Q:What inorganic salts are needed for seeds?
Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid
Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
The organic part is cells that produce bone matrix (inorganic) with excess calcium and phosphorus, and break down the bone salts when the calcium is needed elsewhere in the body. The inorganic matrix provides protection, support and structure for the body. And, actually, red bone marrow is the place where formed elements of the blood are manufactured. Dude, this is not exactly botany. :-P
Q:How can experiments prove that there are inorganic salts in the leaves of plants
The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
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
