Formaldehyde

This is a question you might see.

What is the carbon oxygen bond order in formaldehyde? Formaldehyde is CH2O.

The structure is there on the right.

And we want to know what the bond order is between the carbon and the oxygen.

There are examples that break this pattern, though, like the smallest aldehyde, formaldehyde.

Mixing water with formaldehyde produces a solution called formalin.

Formalin helped preserve tissues from decay, so it's what scientists use to preserve tissue specimens in jars.

And not just scientists, artists, too! Damien Hirst exhibited a whole preserved tiger shark! Thinking about inductive effects, the hydrogen atoms on formaldehyde don't do much to stabilize the partial positive charge on the carbon.

So the equilibrium in a formalin solution very much favors the gem diol, not the aldehyde.

In fact, for the air quality, we measure 10 different kinds of air quality.

the monitoring things and also the thermal quality for the air temperature and also humidity and also for the air quality particulates, three particulates and also CO, CO2, CO2, HCHO, formaldehyde.

Yeah.

And also NO2 and something else.

Is it

formalin or what? Formalin, yeah.

So now that we have you here, can you educate our people on what to look out for?

I'm not NAVDAC.

Surface disinfection was thorough, while a much greater degree of penetration was shown than that secured by any other method, unquote.

Formalin may also be used in the disinfection of rooms and their contents by spraying all exposed surfaces.

Experiments made by Kinyoun and others show that formaldehyde gas does not injure the color or textile strength of fabrics of wool, silk, cotton, or linen, and that it has no injurious action upon furs, leather, copper, brass, nickel, zinc, polished steel, or gilt work.

Iron and unpolished steel are attacked by the gas.

And the recent research we are diving into points to a highly specific atmospheric molecule that changes the entire conversation.

Formaldehyde.

Yes, formaldehyde or H2CO.

Now, I gotta say, my immediate reaction to this is pure biological dissonance.

A lot of people have that reaction.

Let's look at another heavy chemical, formalin.

It's an active ingredient in a lot of popular fast-acting itch treatments.

Formalin is highly effective against external parasites and water molds, but it comes with a brutal, purely chemical side effect.

It strips oxygen.

It aggressively strips dissolved oxygen right out of the water column.
