Acid: Acid is a solution that has an excess of H+ ions. It comes from the latin word acidus that means "sharp" or "sour". The more H+ ions, the more acidic the solution will become.

Here are some properties of an acid:
-Taste sour
-Conducts electricity (flows in the form of ions)
-Some acids react strongly with metals
-Turns blue litmus paper red
-Corrosive which means they break down certain substances
Examples of acids:
-HCI (Hydrochloric Acid), H2SO4 (Sulfuric Acid), HF (Hydrofluoric Acid)
-soda: bicarbonic Acid: CO2 + H2O
-citrus: citric aci
-vinegar kimchi: acetic acid
-yoghurt: lactic acid
-vitamin c: absorbic acid
-fertilizer: sulfuric acid
all of those examples above are examples of weak acids
extra information about acid
(0-2: strong acid), (3-6: weak acid), (7: neutral), (8-11: weak base), (12-14: strong base)
suggest why high acidity helps preserve food from spoilage: high acidity helps prevent bacterial growth which is what causes food to spoil
acid disolves calcium which can turn into CO2 gas
Base: a base is a solution that has an excess of OH- ions. bases are substances that can accept hydrogen ions. another word for base is alkali.
Here are some properties of a base:
-feels slippery
-taste bitter
-corrosive
-can conduct electricity
-does not react with metals
-turns red litmus paper to blue
base: __OH eg: NaOH, Ca(OH)2
uses of base:
-mostly for cleaning products
-for your blood
-gives soap ammonia
-chalk and oven cleaner
-plant products which is almost always alkaline
-lye water (water+ash)
