Answer:
Acid is any substance from 0-6
(stomach acid, lemon juice, vinegar, milk, soda, rainwater)
Bases are any substance from 8-14
(egg whites, baking soda, ammonia)
Neutral are 7
(pure water)
Step-by-step explanation:
* Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.
* Bases feel slippery, change litmus blue, and become less basic when mixed with acids.
