Why does my nose run when I'm cold? I could probably look up the answer, but I'm too lazy.

Cold dries out your mucous membranes in the nose, so it works super hard to moisturize the air, plus the condensation from the different temperatures mean you have extra liquid in there.

Thanks

^youtube maybe? I know I used to watch a couple of their episodes on YouTube (specifically meseeks and destroy)besides that I don't know what to tell ya :/



Also I seem to have forgotten how to make a link in text where the text becomes a link to a site.
Like how would I type "70's style luxury cars" and have it where if someone clicked on those words it would send them to this link http://www.latimes.com/business/autos/la-hy-70s-luxury-cars08-2008may08-pg-photogallery.html
I've completely forgotten even though several people have showed me how
Sorry for my incompetence XD

Click the "Insert Hyperlink" button, underneath the italics button. That gives you this.

Code: [Select]

Stick the URL in like this.

Code: [Select]

[url=URLHERE][/url]
Then the relevant text in the middile, so.

Code: [Select]

[url]TEXTHERE[/url]

Thank you thank you thank you

*You want the [url] tag, but other than that, what Amp said.

Oh shit dammit how did I not notice. Fixing.

"A substance that releases hydrogen ions in solution"

That's an electrolyte, right? It's the mention of hydrogen specifically that threw me off.

By specifically mentioning hydrogen ions it makes me think it might be an acid.

[Gatleos]

Yep, looks like it was acids. Thank you!

Alkali, surely? Acids have a lower pH, and pH stands for percentage Hydrogen if I remember correctly?

Or does chemistry have some weird rules in regards to pH and acids/alkalis?

It's actually a logarithmic scale, with pH of 1 being 1.0 x 10^-1 M of H⁺ ions. They're always in equilibrium with OH^- ions, so higher pH means a largersmaller exponent on the H⁺ concentration and by extension a greater OH^- concentration. They're roughly equal in plain water, which is pH 7.

It's an inverse decimal logarithm from concentration. So, pH 14 means 10^-14 mol/liter [H+], and pH 3 means 10^-3 mol/liter [H+]. Unless I forgot what units concentration is supposed to be in.

Ninja'd but I crossed it out instead of deleting it because I relish the opportunity to show that I still remember some chemistry

Like others said, -log₁₀[H⁺], so the lower, the more acidic, the more hydrogen innit.

Who the fuck invented this scale and why did they choose something that seems to utterly arbitrary?

Sørensen, and it's logarithmic because a lot of things in science work more accurately on logarithmic values.

Yeah, it reflects the physical reality of acid/base chemistry really well, and makes certain calculations a lot easier to do.

Ok small random question, I have tried to no end to scrub these yellowish deposits on my teeth near my gum line (mostly on my front teeth) off with my tooth brush but they will not budge. I am pretty sure they are plaque deposits because I have rather poor dental care :/

Does anyone know a good technique for removing them without going to a dentist?
