Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
Q:Why vegetables and fruits contain rich inorganic salts
Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
Q:How too much to eat too much inorganic salt
Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
Q:Anyone familiar with GC? Is it safe to put an alcohol + inorganic salt water mix into a GC?
Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.
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.
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:How to isolate the effects of inorganic salts on enzyme solubility
The effect of inorganic salts on the solubility of the enzyme was studied. The inorganic raw materials were pretreated with inorganic salts to separate the solid-liquid phase, and some of the lignin and hemicellulose were dissolved, and the sulfuric acid and the inorganic salt were added to the cotton Treatment, thereby improving the enzymatic hydrolysis efficiency. Using different amounts of sulfuric acid
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!
Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:The application of various inorganic salts in the human body?
All tissues of the human body contain strontium, is also the main component of bone and teeth, mainly gathered in the ossification of the place, can be strong bones.
