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)
