Is Your Stomach Acid (Gastric Acid) Diluted When You Drink Water?
Short answer: Yes, drinking a lot of water will certainly change the pH of the stomach, but this amount is trivial. However, since your stomach is very acidic, to begin with, drinking water will not dilute it significantly. Also, there...

Acids and Bases, pH and pOH
We've all heard the terms acid and base. What do these mean? Don't just tell me about pH, silly. What structural detail makes a molecule an acid or a base? You don't know? Well, you'd better watch this then. You don't want to be...

Why Are pH Values Only In A Range Of 0-14?
The pH scale is used to determine whether a substance is acidic or basic, and to calculate how strong a chemical it is. A pH value is a number that ranges from 1 to 14 for most common chemicals, with seven being the middle or neutral...
