An
acid
is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.
What is the difference between an acid and a base?
A substance, mostly liquid that donates a proton or accepts an electron pair in reactions.
An acid increases the concentration of H+ ions
. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.

Is milk an acid or base?
Cow’s milk
Milk — pasteurized, canned, or dry — is an
acid-forming food
. Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.

neither acidic or basic
; it is neutral.
What are the 3 types of acids?
Usually acids can be divided into three major types.
First one is binary acid, second one is oxyacid, and the last one is carboxylic acid

What is base give example?
Examples of bases are
sodium hydroxide, calcium carbonate and potassium oxide
