Study Notes
- pH is related to the hydrogen ion concentration of a solution, with a logarithmic relationship and ranges from 0 to 14.
- Acids have a low pH (less than 7) and high hydrogen ion concentration, while bases have a high pH (greater than 7) and low hydrogen ion concentration.
- In neutral solutions like pure water, the pH is 7, with equal hydrogen ion and hydroxide ion concentrations.
- The pH of different body compartments varies, with blood being slightly basic (pH 7.35-7.45) and the stomach being very acidic (pH around 2).
- pH is important in the body as it can impact protein structure and the structure of other molecules by affecting their 3D structure.
