Acids Acid- a substance that produces hydrogen ions in a
water solution. Forms H3O+ ions from the water and the excess H+
ions

Bases Base- Any substance that forms hydroxide ions,
OH― in a water solution.
Feel slippery
Taste bitter
A base is any substance that accepts H+ from acids.

Indicators Indicator- an inorganic compound that changes
color in acids and bases.

Dissociation of Acids When an acid dissolves in water, the negative end of
water attracts positive end of acid.
The acid dissociates; hydrogen combines with H2O to form H3O+.

Dissociation of Bases The positive areas of nearby water molecules
attract the OH of the base.
The base dissociates into a positive ion and a negative ion.
Water molecules do not combine with the ions formed from the base.

Neutralization When acid reacts with a base to produce water.
The neutralization cancels out the effects of the acid and base.

Salt formation A salt is a compound formed when the negative
ions from an acid combine with the positive ions from a base.
