[Aurelia]

Yes Yggy !

exactly right
going to a burner bday and they are making chilli..then the east bay do
so I am making my staple antidote .. key lime pie

none of you remembers the wonderful old joint under the freeways in LA called the Lucky U ?

xoA.

HI Ratty!!

*todays selfie*

you are so gosh darn pretty!

[southern crone]

Ygmir, all that hot talk made you blush.

[robbidobbs]

Good mornIng Bar!

[Simon of the Playa]

good morning robbi, how's shit going with you?

Shit's just happening. I needed a break last night so watched Going Postal instead of making buttons. My right hand needed a night off really. But you certainly win that pissing contest, how are your hands Simon? Those are some mightly gorgeous benches you've been making.

Edited: now I get your above pic. That guy looks like he needs to go to the loo.

Morning Bar.

Fence painting today. Ah well at least the weather is lovely out here and the mulberry tree is not in bloom yet. When it blooms it will try To kill me.

Ran errands, got some pansies for the containers out front. Someone keyed our truck while we were in the parking lot at lunch. Bastard.

OK chemistry majors, riddle me this.

I built a gizmo to flush calcium deposits out of our "Heat on demand" water heater.

Just pumping vinegar through in a loop for half an hour to flush it out.

The vinegar went from clear, to milky, and wound up clear blue about like window washer fluid.

What caused the color changes???

[ygmir]

I would suspect the metal the tubes are made of, combining with the acidic solution created by the vinegar....it took whatever time to dissolve the coating, and once done, some of the metal dissolved and the ions combined with the solution present, to create a compound that either is more soluble in water, or precipitated out else where, leaving the particular compound that is more clear, and, filtered light such that only blue passes through ?

Milky sounds like calcium coming off the heater elements or possibly small air bubbles. This is normal for HW heater cleaning. Blue/Green sounds like copper. If the fitting inside the HW heater are brass cheaply plated over copper then maybe the vinegar could react with the fittings but I don't think a vinegar solution would be strong enough. If your water system is part of your electrical ground system and you have a fairly constant ground fault- low enough not to trip a breaker, then you could get that amount of corrosion.
There are aquarium test kits to check copper levels.

Edited to add: Do you have dielectric unions on the HW heater?

[ygmir]

yeah thinking about it , bubbles could be the milk stuff, and that could easily come from vinegar reacting with calcium carbonate, fizzing, as it were. when the reaction was done, or stopped due to saturation, the fizzing would also stop, and bubble dissipate. And, a mildly acidic solution could ionize copper, for sure. and as Ulisse points out, electrolysis could add to that, and the acidic solution would make it work even better, and, if there is in fact ionic metal in said solution, even a better conductor.
Ulisse brings up good points!

[FIGJAM]

We have very hard water here and the manual says to flush the system with vinegar every couple of years.

Hard water is sort of a catch all, do you know the minerals? usually a calcium salt, but, well it can be lots of things.
I had a well with hard, and caustic water, the metal salt was manganese. Unusual here, in that most wells in this area are acidic and have calcium salts.

[FIGJAM]

The well is 900ft deep and very alkali.

[Patsh]

Alot of silica in our Arizona water.... with calcium. It'll crust up if allowed to dry.

Hi gang!!!
silica, Patsh? interesting. seems that'd be colloidal, prolly not in solution? (trying to remember chem from 35 years ago). Alakali would tend to make me think of calcium, though, carbonate or chloride.

that is a deep well, FJ!! wow.
I"m guess it's down in limestone?

one of the best water treatment tricks I learned, and it proved out, was aerating and storing in a concrete tank. I had the well free pump into the buried tank, with a nozzle on the end of the pipe, to shoot the water into the existing supply, mixing in air as it did. It's amazing what adding the free gasses will do to precipitate out a variety on minerals and such. Leaving an air gap at the top of the tank, and using a float valve to start and stop the well pump, also makes the pump last longer. running steady for a long time, is better than on and off, for the same amount of water. Assuming you don't pump faster or more than the well can produce. Then, pressurize the house with a much cheaper surface pump.

The concrete in the tank is porous and will have a certain affinity for some eletments and compounds, along with static charge from pumping and spraying. It amazed me how quickly the inside of the tank started to change color as things combined there.


*dunce cap off*

ok, then, how about a cartoon?

*how, with a title like this can one resist?*

[Aurelia]

hello Dear Bar !

love it when the talk is about the sexy mixings of combinations
from chemistry solutions to coffee pot cleaning

worked out and happy

xoA.

[Ratty]

Morning bar crowd. You all look so fresh. I'll just have a bit of rum in my coffee this morning.

[Thecatman]

night all!
Was up at 4:30 this morning to go to work for a little OT. My regular time for getting up is 3:30s and it'll be here before I know it to start a new week.

[southern crone]

Nite, Nite.

I get it too, and I'm not surprised he looks that way, robbi......with his eyes that wide, maybe he's wired on 14 cups or so?

I did something really stupid in my grad school days and drank 8 cups of espresso once before studying. I was so wired I got nearly nothing done. However, I did manage to clean the apartment, the car, pack some boxes away, and play some Frisbee that afternoon. Wheeeeeee.......

[ygmir]

*wanders in, starts ECM*
ah, yay! we got some rain! anything is bonus now...........
Hi Rhino! where ya been?

[Ratty]

Morning everyone. Brought my coffee from home but I could use a shot of Metaxa in it. Rained a tiny bit at my house so I can't spread out my tents today. Off to the charity job. Whooooooosh.....

[ygmir]

*wanders in, makes CCC, turns on "open" sign*
Tuesday! well............it's not Monday.

[Elorrum]

not sure what Tuesday means at this point. It's either a second Saturday, or a first Sunday of three days off. I have to find a laundromat, and figure out that routine. Still in topsy turvy land in many respects, but eh, who needs routine? I'll see what the day brings.

Thanks for starting the coffee, ygmir. I guess I'll open the blinds and see if there's any wetness on the ground here.

[Ratty]

Morning Ygmir, morning elorum. (rubbing eyes). It's great to get in here out of the alergywind. HEY! What the heck? Patting the sofa seat all over.This couch is wet. Does the roof leak?
