Acid vs. Base
A substance that donates hydrogen ions versus one that accepts them.
The comparisoni
“Vinegar is an acid — pH below 7. Bases are soapy/bitter, pH above 7 (baking soda, bleach).”
The ruleii
¶
ACID = pH < 7. BASE = pH > 7.
ACID donates hydrogen ions (H+) in solution, has a sour taste, and pH below 7. BASE (or alkali) accepts hydrogen ions, has a soapy feel, and pH above 7. They neutralise each other to form water and a salt. Pure water is neutral at pH 7.
Memory aidiii
Remember it like this
Acid sour. Base soapy.
