What is an acid? - solution has an excess of H+ ions What is a base? - solution has an excess of hydroxyl ions (OH-) What is neutralization? - -process where acid and base are mixed until they become neutral and the PH is 7. What are the two products of a neutralization chemical reaction? - water and salt ( The type of salt depends on acid or base added to neutralize.) What is a weak acid? - an acid that only partially ionizes in an aqueous solution. This means that not every molecul...
