Is it true Coke is more acidic than Pepsi?

[Noriaki]

I figured they would rot your teeth equally, but the other day Hayley told me Coke will rust nails faster than Pepsi will.

Not that I care much about how fast one will rust nails, after all pure water will rust nails, and either which way I'll brush my teeth before it makes a major difference.

But seriously I thought they were about equal in rot-power...

Is it true pepsi is weaker?

 

[Cable God]

I don't know, but I quit drinking carbonated drinks a few weeks ago. Only good 'ole iced tea and water from now on. I feel better lately too.

 

[nakedfrog]

what about lemonade?

 

[Shantanu]

The acid content from the flavoring is probably negligible. I would imagine most of the acidity comes from the CO2 dissolved in the drink, which reacts with water. I don't know where you get this stuff about acidic foods rotting teeth though or coke rusting nails; never heard that before. Sugar rots your teeth.

not so much the sugar, but what is done with the sugar that rotts the teeth.

Bacteria eat sugar and they produce waste that is acidic.

Hey I cited my source

Hayley told me

I don't know what it is that does the rotting...but are Pepsi and Coke equal in rot power?

 

[vi edit]

My Mother has worked in a Dentist office for 25 years and she can tell you that cola's are one of the worse beverages you can drink.

It's a compounded problem. 1st off they are loaded with sugar. Second, they have an acidic property. Third, the carbonation acts as an effervesent and forces the sugar and acid into the small cracks and creases in the enamel of your teeth. Finally, the syrup in the beverage coats the teeth and acts like a protective seal to keep the sugar and acid in.

Bottom line, carbonated beverages high in sugar are BAD for your teeth.

Not all the acidicity comes from the CO2. One of the ingredients is Phosphoric Acid.

Sorry, I don't know if either is more acidic than the other.

amish

 

[Shantanu]

If you're the type to be concerned about your health, you probably wouldn't be drinking Coke or Pepsi in the first place

 

[PassatVR6]

who cares which ones worse than the other, they are both bad for you and we drink them anyway

 

[Noriaki]

<< who cares which ones worse than the other, they are both bad for you and we drink them anyway >>

Nah I don't like Coke or Pepsi, I drink Rootbeer

Heheheheh!

 

[IBuyUFO]

It would be great if Listerine had an effervesent property to it.

 

[Fatdog]

That's why it should always be diluted with Jack Daniels before consumption.

 

[Syborg1211]

I believe Coke is the strongest of all the carbonated drinks. Coke is the worst beverage possible to drink.

 

[Whisper]

No...Jolt Cola has to be one of the strongest drinks out there. It's like getting an IV of caffeine.

Though tea has more caffeine than any of the above (including coffee), so it'll get you good and wired for a long time. Yay.

 

[Shantanu]

I doubt that's true. Tea has 1/4 the amount of caffeine as an equivalent amount of coffee.

 

[GoldenTiger]

I always drink diet .

 

[pg22]

Expanding on GoldenTiger, what about diet? They have no sugar....but does diet pepsi still rot the teeth?

 

[Static911]

dunno, but i always prefer coke over pepsi

[nirgis]

any carbonated beverage with sugar will be bad for the teeth. From there, ones with more sugar=worse for teeth.

 

[xraymongral]

I remember, way back in the days of the original Coke, we put some Coke in a aluminum foil cooking pan, we left it in there overnight, and it ate thru the pan. I don't know if the new &quot;original&quot; formula will do that though.

 

[GoldenTiger]

pg19: Yeah, about as much as normal water would, I think.

 

[GoldenTiger]

Actually, probably slightly more because of carbonation+syrup, but so minute it doesn't matter.

 

[Thom]

The phosphoric acid in Coke and Pepsi is what causes nearly all of it's acidity. Phosphoric acid has a much greater pKa than Carbonic acid.

The primary effect of sugar is to encourage the development of bacteria on the teeth i believe.

Coke and Pepsi rusting nails is a new one for me, this must be a very small effect. In fact i would probably have guessed that an acidified situation would have the reverse effect if pressed.

Rusting of Fe to Fe2O3 goes through Fe2OH via a H20--> H+ + HO- reaction.
shaky memory tho.

 

[pg22]

Thanks tiger!

So the moral of the story is.....drink diet!
