It is often mentioned that water can dissolve a huge variety of compounds of varying chemical characteristics. Declaring a strict number of such molecules would be almost impossible.
It should be said that these compounds cannot be put into a single category.
At first, let's take a look at ionic compounds. Being a polar solvent, water can dissolve many ionic compounds by dissociating them into seperate ions and creating hydrated spheres. Eventhough, there are some ionic lattices that do not dissolve, which we usually call as precipitates.
When it comes to covalent compounds, many ones with asymmetric polar bonds are dissolved in water such as alcohols, amines etc. In rare cases, non polar compounds also partially dissolve in water, such as bromine and iodine.
Generally, it can be also said that, molecules with relatively higher molecular masses, show less tendency to dissolve in water.
What else can I help you with?
Why water dissolve so many different substances?
Water can dissolve so many different substances because water has an unequel distribution of positive and negative charges(polar molecule) which attract many ions and other polar molecules.
Why do charged and polar molecules dissolve in aqueous solutions?
Charged and polar molecules dissolve in aqueous solutions due to their ability to interact with the polar water molecules through electrostatic interactions. The partial charges on these molecules allow them to form hydrogen bonds with water molecules, which helps them become evenly dispersed throughout the solution. This enables them to dissolve and form a homogenous mixture with water.
Does sugar dissolve in water What does this tell you about the nature of carbohydrate molecules in general?
yes. that they can combine with many different molecules beside their selve because they have 4 outer electrons.
Why do many salts dissolve in water?
Many salts dissolve in water because water molecules are polar, which means they have positive and negative ends. When a salt is added to water, the polar water molecules surround the charged ions in the salt, breaking the ionic bonds and causing the salt to dissolve. This process is called dissociation.
Why water dissloves so many different substances?
Water dissolves many substances but its molecules have both a positive and negative side. Each part of the molecule can bond with the molecules of many other substances and create a new solution. This is the reason water is considered the universal solvent.
How many water molecules dissolve potassium bitartrate and why and what is the equation?
Potassium bitartrate is not soluble in water.
What Can Water Not Dissolve?
While ionic compounds and polar molecules dissolve the best in water, nonpolar molecules do not. Example of a such nonpolar substance: oil. Oil forms clumps or beads in water because the nonpolar molescules are shoved together. Why? The water molecules are more attracted to each other than to the nonpolar molecules.
Why did the powdered milk molecules dissolve faster in water than oil?
Powdered milk molecules dissolve faster in water than in oil because milk contains hydrophilic components that are attracted to water, allowing them to easily mix and dissolve in water. Oil, on the other hand, is hydrophobic and repels water, making it harder for the milk molecules to dissolve in oil.
Why isn't water always a solvent?
Water isn't always a solvent because not all substances can dissolve in water. Water can dissolve many substances due to its polarity and ability to form hydrogen bonds, but substances that are non-polar or have larger molecules may not be able to dissolve 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.
Which type of molecules polar or nonpolar dissolve in water?
None. Pure water is a solvent, so water can dissolve many other molecules. The only molecule in pure water in water H2O Water is ionic and can dissociate into Hydrogen (H+) and Hydroxyl (OH-) ions. Tap water can have many other molecules dissolved in it, one of the most common is calcium carbonate, especially in hard water (limestone or chalky) area.
Are non polar molecules soluble in water?
No.Water can't dissolve non-polar molecules. Water is a polar molecule. Since polar molecules can only dissolve with polar molecules, and non-polar molecules can only dissolve with non-polar molecules, water and non-polar molecules don't react together. Exception:- Some very small non-polar molecules can dissolve in water, like oxygen (O2)
