Glossary
Terms that have earned their place
- pH
- A logarithmic measure of hydrogen-ion activity: a lower pH means greater activity, not necessarily a proportionally stronger sour taste.
- Buffering
- Resistance to a change in pH when acid or base is added, arising from the acid-base system in the liquid.
