What is an acid? - Answer-solution has an excess of H+ ions What is a base? - Answer-solution has an excess of hydroxyl ions (OH-) What is neutralization? - Answer--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? - Answer-water and salt ( The type of salt depends on acid or base added to neutralize.) What is a weak acid? - Answer-an acid that only partially ionizes in an aqueous solution. This...
