- Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
- Three by: the beaker close to the glass rod;
- Q:Why are inorganic sodium salts much better soluble in ethanol than potassium salts?
- Sodium ions are smaller cations than potassium ions. Ethanol has a polar bond in the OH, but it also has a nonpolar tail, the ethyl group. So, unlike water, that has two OH groups that are polar and can interact with cations, ethanol has only one, so it requires strong electrostatic attractions to form a hydrogen bond - dipole interaction with any cation that it encounters. Being smaller, the sodium ions have their positive charge concentrated over a much smaller volume, so the polar OH bond in ethanol is more strongly attracted to the concentrated charge of the sodium than to the diffuse charge of the potassium ion, making the salt more soluble in this solvent.
- Q:Inorganic salts are not nutritious
- Nutritional substances are sugar protein fat three nutrients
- Q:Now need to determine the freezing point of inorganic salt solution, what kind of freezing point instrument is more accurate?
- Because a large branch of antifreeze is with inorganic salt solution.
- Q:therefore indigestible..that I should look for organic plant based trace mineral compounds..anyone care to comment?
- All trace minerals are "inorganic". That's what a mineral is. What the article means is that they are inorganic in the sense that the supplements just have mineral compouds, rather than being derived from a food source. That doesn't make them indigestible, but it can mean they aren't as readily absorbed. Vitamins and minerals are ALWAYS absorbed better when derived from food sources, such as eating a balanced diet, then they are by popping a supplement with a mineral compound in it. But if you need supplements, I don't know if there's such a striking difference between regular mineral supplements or "plant-based" whole food supplements. I don't doubt that whole food plant supplements are probably better, but I don't know that they're better to the degree that it makes the regular supplements "terrible". The best source is STILL diet.
- Q:What are organic and inorganic salts?
- Salt is a mineral from the Earth. Salts similar to iodized are extra munufactured and aren't fully typical. However salts like sea salt have the leat amount of processing. Some say that sea salt is healthier since it's he most traditional state of salt that you could get in mass production. I wolud must agree with them.
- Q:What inorganic salts are needed for seeds?
- Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid
- Q:Plant needs the largest amount of the three major inorganic salts have any effect
- Q:What is the difference between organic salt and inorganic salt?
- An organic salt contains a cation or anion that is derived from an organic compound (compounds that contain carbon), e.g. acetate (anion) from acetic acid, or triethyl ammonium (cation), from triethylamine. An inorganic salt is one that doesn't contain an organic cation or anion. Carbonates are not considered organic compounds, even though they contain carbon.
- Q:I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!
- 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 /cyber/kidswrld/plan...
