Water is a polar molecule. This means that it has a slightly positive charge at the hydrogen atoms and a slightly negative charge at the oxygen atom. Because of this, water is able to dissolve other polar molecules.
When two polar molecules come into contact with each other, they are attracted to each other and form a bond. This process is called hydration.
Water is also able to dissolve non-polar molecules.
In order for this to happen, water must first surround the non-polar molecule in order to break apart the bonds that hold it together. Once the bonds are broken, the water molecules can then work their way inside of the non-polar molecule and cause it to expand. This process is known as solvation.
Water is a solvent, which means it has the ability to dissolve other substances. This is because water molecules are attracted to other molecules, and they work together to break apart the substance being dissolved. The more attraction there is between the water molecules and the molecules of the substance being dissolved, the faster the dissolution process will be.
Why is Water Considered to Be the “Universal Solvent”?
Water is considered to be the “universal solvent” for a variety of reasons. For one, water is very polar, meaning that it has a strong ability to attract and hold onto other molecules. This allows water to break apart and dissolve other substances easily.
Additionally, water is abundant and can be found in nearly every environment on Earth, making it readily available for use as a solvent. Finally, water is relatively safe and non-toxic, which makes it an ideal choice for many industrial and household applications.
How Do You Dissolve Substances?
There are many ways to dissolve a substance. The most common way is to use water. Other liquids that can be used include alcohol, vinegar, and lemon juice.
The type of liquid you use will depend on the type of substance you are trying to dissolve.
For example, salt will dissolve in water but not in oil. Sugar will dissolve in both water and alcohol.
Some substances, like baking soda, will dissolve in any liquid.
To Dissolve a Substance in Water:
1) Fill a container with enough water to cover the substance you want to dissolved.
2) Add the substance to the water and stir until it is fully dissolved.
3) If necessary, heat the water to speed up the process.
What Molecules Does Water Dissolve?
Water is a polar molecule, meaning that it has a slight negative charge on one side and a slight positive charge on the other. This gives it the ability to act as a solvent, dissolving other molecules that have opposite charges.
Some of the most common molecules that water dissolves are salts, such as sodium chloride (table salt).
Other examples include sugar, acetic acid (vinegar), and ammonia. Water can also dissolve some non-polar molecules, such as ethanol (alcohol) and carbon dioxide (the gas that makes soda fizzy).
Conclusion
Water is a polar molecule, meaning it has a positively charged end (the hydrogen atoms) and a negatively charged end (the oxygen atom). When water molecules come into contact with another substance, they will orient themselves so that the positive ends are near the negative ions of the other substance. This creates an attractive force between the water molecules and the ions of the other substance.
The more polar the molecule, the more easily it will dissolve in water.
