Q:Inorganic salt effect
1. constitute the body tissue material .2. Regulate the physiological function .3. To participate in the regulation of body fluid balance and maintain the body's acid-base balance .4 cells of some complex compounds of the important components
Q:Can inorganic salts act as stabilizers for emulsified asphalt?
can. The general use of calcium chloride and ammonium chloride more stable emulsifier
Q:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?

Apple, pipa, durian, citrus, Watermelon, kumquat, peanuts, I know so much. Oh, there are: lotus lotus which contain inorganic salts
Q:Why is sodium chloride(salt) an inorganic compound?
Yes it is considered to be organic only if the compound contains carbon. Oxygen and Hydrogen have no bearing on that, for example CO2 is organic, whereas H2O is not.
Q:How does inorganic salts maintain osmotic pressure and pH
PH ~ inorganic salts of carbonates bicarbonate, hydrogen phosphate / dihydrogen phosphate, can help regulate the pH value of the internal environment, even if the external environment Zoumu changes, the environment will not change too fast, there will be a Buffer room
Q:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
