Is Dihydrogen Monoxide or DHMO Dangerous?

Every now and then (usually around April Fools Day), you'll come across a story about the dangers of DHMO or dihydrogen monoxide. Yes, it's an industrial solvent. Yes, you're exposed to it every day. Yes, it's true. Every one who ever drinks the stuff eventually dies. Yes, it's the number one cause of drowning. Yes, it's the number one greenhouse gas.

Dihydrogen Monoxide

Other uses include:

• flame retardant chemical
• food additive
• component of pesticide sprays
• torture in World War 2 prison camps
• to make chemical and biological weapons

But is it really so dangerous? Should it be banned? You decide.



Here are the facts you should know, starting with the most important one:

Dihydrogen Monoxide or DHMO Common Name: water

DHMO Chemical Formula: H2O

Melting Point: 0 °C, 32 °F

Boiling Point: 100 °C, 212 °F

Density: 1000 kg/m3, liquid or 917 kg/m3, solid. Ice floats on water.

So, in case you haven't figured it out yet, I'll spell it out for you: Dihydrogen monoxide is the chemical name for ordinary water.

Instances Where Dihydrogen Monoxide Really Can Kill You

For the most part, you're fairly safe around DHMO. There are, however, certain situations where it truly is dangerous:

1. While dihydrogen monoxide contains oxygen, each molecule only contains one atom. You need O_2 to breathe and carry on cellular respiration. So, if you try to breathe water, you could die.
2. If you drink too much water, you can suffer a condition called water intoxication or hyponatremia. People have died from it.   
3. There are different forms of water. Heavy water has the exact same molecular structure as regular water, except one or more of the hydrogen atoms is replaced with deuterium. Deuterium is hydrogen, but each atom contains a neutron. You naturally drink a tiny bit of heavy water with regular water, but if you drink too much of the stuff, you'll die. How much?
