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:give me examples of organic, inorganic, acid, base, salt.?
an inorganic substance usually contains no C NaCl refer to salts list and an organic does usually CH4 C2H6 C3H8 C4H10 C5H12 acids usually release H+ ions H2SO4 CH3OOH HCl H3SO4 HF bases usually release OH- ions NaOH Mg(OH)2 KOH LiOH Ca(OH)2 salts are usually just ionic compounds NaCl KCl NaI KI NaBr
Q:Can inorganic salts be tested by LC / MS?
LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
Q:People lack the inorganic salt will be what disease

2nd place: pecan (cooked) [walnut] (12.59 / 30g / 100g)
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:What is the use of inorganic salts and organic salts?
The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
