Question

What atoms are in water?

Answer 1

Well, for a start, hydrogen and oxygen in a 2:1 ratio, hence `H_2O`.

Explanation:

The molecular formula of water is (as of course you know!) `H_2O`. The water molecule (as of course you know!) thus has 2 hydrogen atoms per oxygen atom.

And of course water is an excellent solute; it can dissolve both ionic and non-ionic solutes.

The boiling point of water is `100` `""^@C` at atmospheric pressure, which is unusually high. This is much higher than comparable molecules, `NH_3`, `H_2S`, `SO_2`. The degree and extent of hydrogen bonding that occurs in water, as an intermolecular force, can rationalize water's unusual properties as a solvent.
