Water itself is simply a molecule containing two hyrdogen atoms and one oxygen atom bound together, i.e. "H2O". Water, whether municipal or from a river, lake or other source, can have any number of mineral and chemical impurities in it.
They are soluble substances, which would include polar substances and ionic compounds.
Any substance that dissolves in water, increases the conductivity of water. The most effective substances are salts.
Substances that dissolve in water are soluble. Soluble substances will be polar because water is also polar. Those substances that do not dissolve in water are insoluble, which are nonpolar.
b. chemical substances
When chemical substances are dissolved in water, this is called an aqueous solution.
Water. That is because water is a compound and compounds can only be separated by chemical means. Salt water is a mixture, and sodium and gold are both elements. Hope this helps!
Substances interact with other substances by chemical properties
Some substances are soluble. This means they are able to dissolve into other substances. Sugar, for example, is soluble in water, however, vegetable oil is not. This has to do with their chemical makeup.
No. Abundantly no. dissolving is a physical process, it does not modifies the chemical structure of substances
studyisland answer : water
Dissolution is a physical process.
No. That would be a chemical property.
Chemical substances such as nitrogen, oxygen, argon are a mixture that are found in the atmosphere. Carbon dioxide and water are also found depending on the climate and altitude.
It is called as a chemical reaction, a familiar example is the reaction between an acid and a base to form a salt and water.
These substances are called reactants.
Chemical affinity can refer to the tendency of an atom or compound to combine by chemical reaction with atoms or compounds of unlike composition. Example, sodium and chlorine, NaCl (table salt) Substances that have an affinity for water are hydrophilic, those that seem to repel water are hydrophobic Google hydrophilic substances and you will probably get a decent answer
H2O is the compound water. Forming it from other things would be a chemical change. Using it to react with other substances and form new substances would also be a chemical change. But water just sitting there is not a chemical change. EX: hydrogen(gas) + oxygen(gas) forms water (chemical change) Water + sodium forms sodium hydroxide and hydrogen (gas) (chemical change) BUT water + sugar makes a sugar water solution (not a chemical change) nothing new was made, the sugar just dissolved and the water is still water
