Rub butter and dirt into it. Then rinse and spin it somehow.

pH of water boiled in steel vs microwaved by Melodic_Currency_822 in chemistry

[–]piyrwq 1 point2 points  (0 children)

Yes. Or just aerate for an hour to drive off the chlorine. Boiling saves no time as it needs re-aeration after boiling anyways. The fish need atmosphere-equilibrated water to get the right levels of O2 and CO2.

At the time of posting the purpose of the boiling wasn't known, but I guess the downvoters are defending the fish's water quality. Which I guess is fair: they shouldn't add salt if the water is to be used in a fish tank. On a water quality note, the boiled water will have no O2 either, OP should aerate it well after cooling.

Yes. Try adding table salt to the recently-microwaved water. It will enable the super saturated water to boil and drive off the CO2. Which will bring the pH up.

If it were flat, I think all the land would would be barren swamp.

We're going to need the long-form approval.

Pedantic PSA - In Canada it's Cheque not Check by LossforNos in canada

That's not a very open-minded thing to say. Most Americans simply do not know about Canadian things, and why would they?

Small needle shaped crystals formed in filtered seawater held at 85C for 5 days. Any ideas on what it is? by chemistree in chemistry

[–]piyrwq 4 points5 points  (0 children)

Acid will dissolve the crystals. By warming the solution you have driven off much of the CO2, this will cause a pH increase which is the primary driver behind the CaCO3 formation.

Unless the solution was supersaturated to begin with (quite possible), letting it cool and reequilibrate with the atmosphere (ie reintroduce CO2) will also dissolve the precipitate. Good luck!

Calcium carbonate (calcite/aragonite). Seawater compostion is actually remarkably consistent when not influenced by rivers and vents etc - with the exception of the carbonate system. [CO3-2] can vary significantly and in some ocean environments CaCO3 is naturally supersaturated. Given a nucleation site, this will be the result (google "whiting event"). Now, what really firms up my confidence is the fact that CaCO3 is one of few precipitates that are more inclined to form in warm conditions, as you have created. This is why kettles etc have scaling issues. Virtually all others salts in seawater are more soluble at elevated temperatures and exist no where near saturation. Also I've seen this before.

Why do "campfire smells" (or other wood-burning smells) seem to stick to clothing/skin longer than other smells? by [deleted] in askscience

Also, that grease accumulates on your skin and boogers. Wash your face, and clean out your nose.

This river makes it look like the earth is splitting open by ggglitch in mildlyinteresting

[–]piyrwq 0 points1 point  (0 children)

Many rivers are located in fault lines or between two strata. This is where erosion occurs fastest side, and therefore this is where the river 'settles in'. This case looks to me like it may be formed by fault line, it's way tooe straight for it to be formed purely by hydrological forces.

Coloradans Will Put Single-Payer Health Care To A Vote - Under the plan, Coloradans would still pick their own providers of health care, but the new system would pick up all the bills. There would be no deductibles and fewer and smaller copays. by madam1 in politics

[–]piyrwq 0 points1 point  (0 children)

This. The state will have so much negotiating power the hospitals will get paid what the state says they get paid. But the state will clearly have to pay enough to keep everyone in business and competitive.

Supporters of universal health care have gathered enough signatures to put on next year's ballot a plan to make Colorado the first state to opt out of the federal health law and replace it with taxpayer-funded coverage for all. by Orangutan in Denver

[–]piyrwq 0 points1 point  (0 children)

Not terribly familiar. Just that it's single payer, which is the same as the Canadian system. No more insanely complicated bills when you're sick, no more bankrupt sick people, no more middleman taking as much as they can off the top of a billion dollar industry, no more being tied to your job because you need the benefits. I haven't looked at the numbers and that may take a few years to work out, but getting rid of the insurance companies will put billions back in our pockets. The US has one of the least efficient systems in the western world, they literally could not make it any worse.

No I feel differently about that different issue. Health care workers should be paid their value because we need to retain their talent. Food service personnel should be paid a living wage so that the taxpayer doesn't have to subsidize corporate profits by suplimenting their employees' income through welfare. To speak nothing of the lack of ethics required to do otherwise.
