I setup the above test in between titrating a 5L flask of 0.01M NaCl to pH 5 and moving pH's for some mobility samples. I used the cutest mini-beaker ever for the Mountain dew and because we're an amazing lab, the meter was recently calibrated. The results are accurate.
*Warning: This. May. Shock. You.*
Right. So, I've followed up my research with this website: http://www.21stcenturydental.com/smith/pH_drinks.htm . It compares more sodas and their data seems to think that Mt Dew is actually a pH of 3.22.
- Are any sodas worse than Mountain Dew? Yes. Obviously because Mountain Dew is amazing. A short list includes: Coke original, Battery Acid, Capri Sun, Gatorade, Pepsi, Country Time Lemonade, Lipton Brisk, Hawaiian Punch, Dr Pepper, Propel, Snapple Tea, Code Red, and many more.
- What else can we compare this to? Stomach Acid is usually around a pH of 2. Water is pH 7.
- How bad is this for your teeth? Ok it's bad. "Demineralization, or loss of tooth material, begins at a pH of 5.5"
- Well, I'm a smarty pants that wants to pick on you more about your Mountain Dew consumption. Isn't it also true that Mountain Dew has an extraordinarily high amount of sugar? Oooooh where'd you hear this? The smart people store? Mountain dew has 46 grams of sugar. BIG DEAL. It's the best tasting stuff ever. So. There. There's more carbonated water than high fructose corn syrup (WATER!!) AND the third most present ingredient in this beverage is concentrated orange juice. Fact.
- I'm guess this new information will stop you from drinking it, right? Guess again.
