a precipitate may form
What is a double replacement reaction involve?
a precipitate
What happens in a double replacement reaction and what is another name for it?

What is a base?
any compound that will accept a hydrogen ion in a chemical reaction
When is an aqueous solution is considered acidic and what solution is considered basic?
acidic-when the H30 ion concentration is greater than the OH ion molarity, and basic when reversed

in a base
What is an acid/base reaction?
when the acid donates a hydrogen ion to the base to yield a product
What is titration used for? and what is it?
it allows to find the amount of either the base or an acid, involves the addition of known conc. to unknown concentration until equiv.
