What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
What is the nature of the substances dissolved in water?
Substances that dissolve in water are polar molecules, like water. Also, many ionic compounds can also dissolve in water as well, such as common table salt, NaCl.
Can gases cannot dissolve in water?
To find out the answer to this question, first you must understand about polarity. A polar molecule is one which has both: -polar bonds (ie. the intramolecular covalent molecular bond between both atoms are of different electronegativities, hence one gains a partially positive charge, delta +, and the more electronegative atom gains a partially negative charge, delta -). -the delta + and delta - centres to not coincide (and therefore do not cancel each other out) (need to know molecular structure to do this) Both of these mean that the molecule has an overall dipole (+ive and -ive side) Polar molecules are soluble (can dissolve) in other polar solvents. Non-polar molecules are soluble in other non-polar solvents. A polar substance is NOT soluble in a non-polar substance and vice versa. WATER IS A POLAR SUBSTANCE. Therefore, gases which are ALSO POLAR can dissolve in water.
Why does salt dissolve and sand doesn't?
Water is a polar molecule. you may have heard water being called H20. This is because it has two hydrogens (slightly positively charged) and one oxygen (slightly negatively charged) in a molecule. Salt/Sodium Chloride/NaCl is also polar and that is the reason why it dissolves in water. Sand doesnt because it is not a polar molecule, it is just crushed rock. Hope that helps!
Name a molecule that does not dissolve well in water?
oil does not dissolve at all in water.
What does so2 dissolve in?
It dissolve in polar solvents.It dissolve well in water.
What type of molecules mix the best with water?
Molecules that are polar(charged) dissolve best in water, while nonpolar molecules do not dissolve well in water.
Why does methane not dissolve well in water?
Methane is a non polar molecule and water is a very polar molecule. Therefore, one will not readily dissolve in the other.
Do mono saccharides dissolve well in water?
Monosaccharides will dissolve well in water. This is made possible by the oxygen in the carbohydrates which will create polar bonds.
What kinds of molecules do water dissolve?
It dissolves all kinds of molecules. However, the ones that it dissoves well are molecules that it can hydrogen bond with or molecules that are polar that it can have dipole-dipole interactions with.
Why are fatty acids -or oils or fats - not soluble in water?
They are non-polar and therefore don't dissolve well in polar solvents (like water).
In which solvent do you expect a solid that ionizes well to dissolve in?
Water or another polar solvent.
Which of the following would be most soluble or miscible in cbr4 and which one will be more soluble in water A. NaCl B. HCl C. CH3OH D. CH4 E. C2H6?
Polar molecules dissolve in polar solvents (like water), and non-polar molecules dissolve in non-polar solvents (like CBr4). NaCl and HCl will both dissolve in water, and CH4 and C2H6 will dissolve in CBr4. CH3OH will likely dissolve in water as well. ---------- Methanol is soluble/miscible in water at all concentrations. It will likely also interact well with non-polar solvents like Tetrabromomethane. Keep in mind that methane and ethane are gasses at STP, but should dissolve well in Tetrabromomethane in the right conditions.
What is the substance that would not dissolve well in water and why?
A nonpolar substance, such as vegetable oil, would not dissolve well in water because water is a polar molecule and dissolves other polar molecules and many ionic compounds, but not nonpolar substances.
If water were non polar molecule how would its properties be different?
A nonpolar liquid cannot dissolve polar molecules.
Does salt dissolve in alcohol?
Alcohol is a non-polar solvent and does not dissolve salt as well as water does. If there is water in the alcohol then some of it will dissolve.
What is the nature of the substances dissolved in water?
Substances that dissolve in water are polar molecules, like water. Also, many ionic compounds can also dissolve in water as well, such as common table salt, NaCl.
