Q:How long will it take for epsom salt to be incorporated into a plants rate of photosynthesis when addedto soil?
Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr.gov/cyber/kidswrld/plan...
Q:A colorless solution contains which inorganic salt?
Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
Q:The exact definition of mineral salt?
it okorder.com/C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "
Q:Nutritional characteristics of carbohydrates and inorganic salts in vegetables
Inorganic salts: its rich, such as calcium, phosphorus, iron, potassium, sodium magnesium, copper, is an important source of inorganic salts, to maintain the body's role in acid-base balance play an important role. Green leafy vegetables generally contain more than 100mg / 100g. But should pay attention to the removal of part of the oxalic acid during cooking, may be conducive to the absorption of inorganic salts.
Q:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
Soy products containing more calcium. Animal liver, spinach iron, zinc and so on.
Q:What is the most important inorganic salt in plant growth?
The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.
Q:Inorganic salt is not salty
HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
Q:The application of various inorganic salts in the human body?
Silicon in the water was partial silicic acid form absorbed by the body, mainly distributed in human skin and connective tissue, in the process of skeleton has a physiological role in promoting the development of bone development. Silicon is also involved in the metabolism of polysaccharides, is to form some glucose The main component of the aminopolysaccharide carboxylic acid.
Q:What to eat can promote the absorption of inorganic salts
The active transport of the carrier consumes energy, while the respiration provides its energy
Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
