ARE YOU SMARTER THAN A 5'th GRADER ?

[Dre]

What does the letters p,H in pH mean ?And please don't cheat be honest.If you read this thread please give an answer, if you don't know say you don't know and so on.Thanks for participating.

 

[Killerdrgn]

Don't forget that it's supposed to be pH not PH, ph, or Ph.

I'm not smarter that 5th grader but I can GOOGLE...Enjoy:sgrin:

Did they give the easy answer or the hard one?

 

[ryangrieder]

id like to peek on this one if i may mr foxworthy! lol

"p"otential of "H"YDROGEN ... ("p"otenz "H"ydrogen)

OK ,so what's the answer?

 

[Killerdrgn]

Too late, it's already been answered, unless you want it in Latin.

 

[knugenx]

linky for simple explanation

You had your chance LOL.Thank for participating everyone,35 to 1 :scratch:not so sure.

I had no idea.. I'm not smarter then the 5th grader that answered it without googling it,,lmao..
Dave should erase his answer so others don't know the answer..

Thanks for being a good sport, i didn't know the answer either i thought there would be more members involved though.Oh well, i guess no one what to say ''I'm not smarter than a 5'th grader'' lol.

I think the most accepted answer is powers of Hydrogen. Though it's really a negative power.

Did you actually ask any 5th graders? lol

Let's take this to the next step - if you don't mind the slight hijack Dre

Can't say that I knew (or recalled) what pH stood for, but I do know how important a parameter it is to our tanks.

Here is an information link of some info about pH in marine tanks..
http://www.aquaticcommunity.com/marineaquarium/ph.php

While interesting - it does not explain why pH is so important to the health of our FISH :fish:

We concentrate so much on Ca/Alk/Sg for our corals but when it comes to fish most of the talk is on issues like Ich and feeding. Fluctuating pH is the easiest way to stress/kill a fish.

Do you know why?

 

[KathyC]

wow..50 more views on this thread since I left for work this morning and nobody knows why PH is so important when it comes to our fish?

...cheating is permitted :flirt:

 

[motortrendz]

im, lurking and waiting kathy... lol this is y i love the forum.. the learning part.. not the drama part...lol

whats the answer.....

 

[KathyC]

im, lurking and waiting kathy...

whats the answer.....

6 minutes later and you want me to post the answer? ...file that under fat chance my friend :kiss:

This really is a topic reefers should be well aware of...:sigh:

 

[motortrendz]

im a patient man... lol besided my google goggles(unlike some people) arent working today.. lol ill be lazy and wait..

Kathy, the question was actually asked on the Are you smarter than a 5'th grader game show on Fox Monday evening.

The metabolisim of living organism affect water chemistry in two basic ways ,1.Gas exchange mostly oxygen and carbon dioxide and 2.Exchange of dissolved nutrients nitrogen ,phosphorus and a variety of micronutients.Animals release feces, plants lose parts and so on.They all excrete organic compounds such as ammonia .These processes use oxygen,release carbon dioxide and produce nutrients.In marine ecosystems oxygen is generally the most important of the two gases. Carbon dioxide CO2 reacts with water to form carbonic acid.
In water significantly affected by the activity of organisms much more carbon dioxide will be dissolved than oxygen. Carbon dioxide bicarbonate,carbonate,hydrogen and pH present in any given water mass is a function of the interaction of several chemicals equilibria:temperature,salinity and pressure.Conditions can be determined by testing for pH,ALK,CO2 etc. Sea water is strongly buffed for pH and generally ranges from 8.00-8.40.Because of the ions present ,great changes in carbon dioxide are necessary to affect a small change in pH although most marine organisms are particularly susceptable to small pH changes and in this respect the environmental status is crucial.
As sea water flow in over a reef driven by constant winds it pick up extra oxygen during the day because of excess photosythesis.At night the same water loses oxygen due to the respiration and with out photosythesis of both plant and animal this lowers pH levels.
A reef environment, pH ranges from about 8.10 -8.30 with early morning pH at about the lower end and late afternoon or early evening at the upper end of the range.
