Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.
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:Chemical formula The longest inorganic salt
The primary stage on the salt, acid salt and so on
Q:Does the apple contain inorganic salts and vitamins?
Yes, the fruit is rich in these two nutrients, especially apples
Q:What does salt form when it dissolves?
Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
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:What cells produce the collagen and inorganic salts of bone matrix?
The collagen is produced by chondrocytes. The minerals that make up the bone are precipitated by osteoblasts.
Q:Is bromine an inorganic salt?
Bromide is an anion which joins with a cation to make a salt like Sodium Chloride (table salt) Bromine is a liquid bleach, similar to chlorine gas. oganic compounds are those which have carbon or sulphur base
Q:What is the difference between organic salt and inorganic salt?
one is organic while the other is inorganic
Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
Dr. Henry A. Schroeder, the world's mineral authority, says that the minerals required by the human body are present in the water, meaning nothing more than those that exist in food.
