How does water dissolve a molecule?

How does water dissolve a molecule?

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.

How does water actually dissolve polar molecules?

So the partially negative part of one polar molecule (like water) will interact with the partially positive part of another molecule (like your mystery substance). This allows polar substances to dissolve each other. They are non-polar, so there is little for the polar water molecule to be attracted to.

How do water molecules dissolve a salt apex?

Salt (sodium chloride) is made from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions.

Why do organic compounds dissolve in water?

When there are hydrogen bonds ( F-H , O-H , N-H , Cl-H bonds can make hydrogen bonds ) between organic compound and water molecules, ability of dissolving in water is high. Organic compounds such as alcohols, phenol, aldehyde, ketone, carboxylic acids, amines and more can make hydrogen bonds.

Why the polarity of water molecules makes water a good solvent?

Water is a good solvent due to its polarity. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute. The partially negative dipoles of the water are attracted to positively charged components of the solute, and vice versa for the positive dipoles.

Can water dissolve ionic molecules?

Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.

How does water molecules dissolve a salt?

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
