What allows water to dissolve salt and sugar?

Answer 1

Salt and water both have what we call polar molecules. That means the electrons in the molecule are not divided equally between the atoms of the molecule. This causes partial charge on the molecules atoms. Look up 'why do salt dissolve in water?' if you are confused. I'm just stating an answer. :) Good luck!

Answer 2

1. Water, H2O, is a polar solvent, therefore, it will dissolve polar solutes.
2. Polar means that there are negative and positive areas in the molecule that will "support" negative and positive areas in the solute.
3. Water is a liquid due to the attractive forces between the water molecules. These attractive forces occur because the electron poor hydrogen in the molecule is attracted to the electron rich oxygen in neighbouring molecules.
4. Salt eg NaCl, has the positive sodium ion and the negative chloride ion to be supported by the negative and positive areas of the water molecule (electron poor hydrogen is positive and electron rich oxygen is negative).
5. Sugar is a bit more complicated. Sugar has many O-H bonds just like water so water can support its molecules due to the O-H bonds. They line up in the water with the slightly negative O being attracted to the slightly positive H in the water and vice versa.

Answer 3

Water is a polar molecule, which means it has both positive and negative ends. Salt and sugar molecules are ionically bonded, so when they come into contact with water, the water molecules surround and pull apart the salt or sugar molecules, allowing them to dissolve.

Answer 4

The water molecule is attracted to the salt, which is made up of sodium and chlorine. The water molecules then surround the salt and causes it to slowly dissolve.

Answer 5

Atoms of an element may have different numbers of neutrons, these atoms are called iso tapes of elements.
