What substances will dissolve in water?

Answer 1

Good question! This is Biology. Two substances i know for sure dissolve in water are salt and sugar.

Water and salt both consist of what we call polar covalent bonds. This means electrons in the molecule are not equally shared between the atoms of the molecule, causing a partial charge on the molecule's atoms.

Water, for instance, contains two hydrogen atoms and one oxygen atom. The oxygen atom has a stronger pull on the electrons being shared, hence giving it a slightly negative charge.

Since electrons are negatively charged, the oxygen part of the molecule is partially negatively charged and the hydrogen parts of the atom are partially positively charged.

In salt, which is made of sodium and chlorine, the shared electrons spend almost all of their time on the chlorine side, making the chlorine negatively charged, and very little time on the sodium side, making the sodium positively charged. Just like the oxygen atom, the chlorine atom has a stronger pull on the shared electrons.

When salt is put into water, the positively charged side of water molecules surround the negatively charged chlorine, and the negatively charged side of the water molecules surrounds the positively charged sodium. ( you know the saying "opposites attract") This breaks the sodium chloride bond and the salt is dissolved.

Answer 2

Water is an extremely versatile and powerful solvent, in which countless thousands (or possibly millions) of different substances will dissolve. It is classified as a polar solvent because the water molecule has positive and negative poles. It is most effective in dissolving other polar compounds.

Answer 3

the substance can disslove in water (h2o) are most

POWDER.

Additional answer

A powder is no more or no less able to dissolve in water than if that substance were NOT a powder. Powdering something does not help to make it soluble, though it might make it dissolve more quickly if it's able to dissolve at all.

Some substances that dissolve to some extent are salt, sugar, calciul sulphate, copper chloride - millions of things

Answer 4

Water is almost considered a universal solvent. Most substances will eventually dissolve in water. Any substance that is soluble in water is polar, since water itself is polar. But that means that any non-polar substance such as a lipid (oils, waxes) will not dissolve or at most in very minute amounts.
