Salt evaporates???

[lilrobb]

Just finished cleaning the ducts of my exhaust fan (mounted 10' above ground), and I couldn't believe the amount of THICK salt crystals I found in there - how did they get there?
Guaranteed no splashing up there!

 

[rolo65]

the NaCl molecules are minute enough to be trapped in the evaporate...same thing occurs if you go to the beach and you get a salt film on your windshield...and considering the amount of saltwater in your fish room prior to cutting out that wall.....not surprising that there was a thick layer

 

[lilrobb]

Ahhhh, makes sense.
Opened the duct and was literally snowy white w crystals...

Salt fairy:yay: seriously though some must evaporate just going by the amount that accumulates on light fixtures, canopies etc. I'm certainly no chemist though

 

[rolo65]

yeah and having that duct pulling the majority of the evaporate though there...itll accumulate much faster in there than it ever would on fixtures and such....so id say start checking it periodically.....but hey....now you dont have to buy Sea Salt at the grocery any longer....

I noticed this phenomenon once myself. Look up the word "hydroscopic" it is the explanation I was given. Who cares just clean the vent man.

Hygroscopic, means a dry material attracts humidity - not sure that applies here.

hydro......


and im just stating what he said.....

Hydroscopic is no word, there is a scientific tool called a Hydroscope, though...

 

[rolo65]

i know....and you may need one once you get the new tank set up....call it a fated post?...lol...or maybe just a fated misspelling....but yeah you will probably need one....

LOL
Glad nobody here said "shop vac", haha

Aerosols from the ocean travel many miles over land, so it should be no surprise to have them deposited in your ductwork. I'm betting your (our) skimmers produce a lot of these!

It was a teacher of mine years ago that told me about it. Rolo answered the question better. I figured that couldn't happen if salt were not hygroscopic.

I could be wrong but in the car world hygroscopic can relate to a liquid. Brake fluid is hygroscopic. It absorbs water. I doubt think it only applies to something dry.

You're right it means "attracts water", not only in solids...

yup.....disinfectants are also hygroscopic....and your skin.......ahhhhhhhhhh

Hygroscopic.....it puts the lotion on the skin.

It will absorb humidity out of the air... I've heard hygroscopic defined as "attracting" moisture more than absorbing. Take a beaker of brake fluid, put outside and come back later... the fluid level in the beaker will have risen.

That's magic......not science.......but then again some ppl think they're the same thing
