Properties of Water


Water is a solvent that can dissolve many substances.

NaCl is the chemical compound that we call table salt.

Molecules that are polar and which are attracted to water are hydrophilic (ex. sugar, salt).

Molecules that are non polar have no charges cannot attract water. These are called hydrophobic (ex. oil, grease, fat).

Water dissolves polar substances and ions.

Water molecules stick to each other and to other substances



 

Water also has a high surface tension.



The stronger the force between molecules in a liquid, the stronger the surface tension.
