reefer123 Posted November 22, 2008 Share Posted November 22, 2008 ok so heres how i see it, i am dosing kalk in top off. this ph is around 12, extremely basic, which is corrosive. if this corrosive mixture ran through a container with calcium reactor media in it, would it act like a low ph calcium reactor chamber and dissolve the Ca media, mixing calcium with aragonite and such?? thus doubleing levels of needed hard coral requirements?? or would more calcium not dissolve in it because it is so calcium rich??? i think this could b a beneficial discovery in saveing money from buying a Ca reactor. please post your thoughts. THANKS ABUNCH Link to comment
lakshwadeep Posted November 22, 2008 Share Posted November 22, 2008 high pH will mean the calcium carbonate (aragonite is one form) would not dissolve. Link to comment
phases Posted November 22, 2008 Share Posted November 22, 2008 Corrosive can be both acidic or alkaline and it the case of kalk which is calcium hydroxide it is alkaline. As you said it has a pH of 12 but calcium carbonite needs a pH of around 6.5 to dissassociate. Link to comment
davidncbrown Posted November 22, 2008 Share Posted November 22, 2008 high pH will mean the calcium carbonate (aragonite is one form) would not dissolve. You're confusing the pH scale. corrosive = acidic. caustic = basic = kalk = wouldn't work. Sorry, but you have it backwards. Would be cool if it worked like that though. Link to comment
er1c_the_reefer Posted November 22, 2008 Share Posted November 22, 2008 it won't dissolve. the reason ca reactors work is because of the carbonic acid produced when mixing CO2 and water. the acid in turn dissolves the media. basically put: CO2 + H2O <=> H2CO3 <=> 2H+ + 1 carbonate 2H+ + 2CaCO3 => 2calcium + 2H20 + 2CO2 edit... its like CaCO3 + CO2 + H2O → Ca(HCO3)2 Link to comment

I hate writing them without subscript. Drives me nuts. How sad is that. Link to comment

davidncbrown Posted November 22, 2008 Share Posted November 22, 2008 So, you quoted me, you were addressing reefer123? ya I know, I was just lazy and didn't want to scroll down. I was just gonna delete the quote. My bad Link to comment
TheUnfocusedOne Posted November 22, 2008 Share Posted November 22, 2008 agree not so much gotta love basic chem Link to comment
lakshwadeep Posted November 22, 2008 Share Posted November 22, 2008 Thanks for the equation. I hate writing them without subscript. Drives me nuts. How sad is that. Just because I'm a biochem major, I'll write it out, subscripts and all. CO₂ + H₂O ⇋ H₂CO₃ ⇋ 2H⁺ + CO₃²⁻ 2H⁺ + 2CaCO₃ = 2Ca + 2H₂O + 2CO₂ Link to comment

reefer123 Posted November 23, 2008 Author Share Posted November 23, 2008 oh my god i thought chemistry class was hard. biochemestry major, that sounds really cool! where at/from? and thanks for all the input guys! Link to comment
lakshwadeep Posted November 23, 2008 Share Posted November 23, 2008 I'm a sophomore at OU, and I am gradually warming up to organic chemistry. The lab is more exciting. We got to ferment ethanol from yeast, purify caffeine from tea bags, extract lycopene from tomato paste, etc. Link to comment

We got to ferment ethanol from yeast, purify caffeine from tea bags, extract lycopene from tomato paste, etc. Organic chem is always a great time, it really is just one giant puzzle figuring out with synthesis gets your product where, and how it'll effect your other substituents on the molecule Inorgs where its out iz be resurchin Ru based photosensitation molecules for possible applications to photovoltaic cells for direct energy conversion or use in photolysis of water molecules into its substiuents to help fuel a possible (probably) future hydrogen economy yeah, inorg is the way to go biochem is... kinda cool...

BKtomodachi Posted November 23, 2008 Share Posted November 23, 2008 orgo ftw. I was grading my latest set of lab reports yesterday, and apparently whoever teaches these people in lecture is an idiot. when asked what would happen if 1/2 the amount of Pd was used in the reaction, they ALL seem to think it would produce 1/2 the amount of product. Note: orgo ftw applies only in the world of chem. bio is FTW with caps, of course. Link to comment
TheUnfocusedOne Posted November 23, 2008 Share Posted November 23, 2008 nerds. YAH I SAID IT. i am, and im loving it chem is the way to go, there something awesome about being paid while attending graduate school you pay me to get my Ph.D? well, if you insist its just awesome to feel part of a epic world changing project that will have massive implications on humanity down the road i mean hell, scientist from USC, MIT, CalTech and a lot of very prestigious institution are all working non stop to solve this problem just being able to be partly on the same level with individuals like Nocera, Gray and Meyer make me all excited and goose bumpy getting back to you statement, yes im a huge nerd Link to comment
adinsxq Posted November 23, 2008 Share Posted November 23, 2008 when did this "orgo" thing start? when i was in school everyone referred to it as "o-chem" orgo sounds stupid. Link to comment

(im assuming your talking about some kind of catlytic reaction liiike the addition of hydrogen to olefins) when did this "orgo" thing start? when i was in school everyone referred to it as "o-chem" orgo sounds stupid. I hear it called o-chem still orgo is just sexier sounding o-chem is harsh and rough oooorgooo mmm... thats nice.... Link to comment
lakshwadeep Posted November 23, 2008 Share Posted November 23, 2008 my school still uses "o-chem". "orgo" sounds like some mating call. Link to comment
