Salts

What is a salt?

• A salt is a compound formed when the negative ions from an acid combine with the positive ions of a base• Neutrilization is a chemical reaction

between an acid and a base that takes place in a water solution, the products of which are water and salts

Acid/Base Reactions

• The general formula for an acid/base reaction is acid + base -> salt + water

Titration• The process in which a solution of known

concentration is used to determain the concentration of another• The standard acid or base solution is added

to the unknown acid or base solution containing an indicator• Slowly add known solution until the entire

solution changes color• At this point all of one substance has been

neutralized• Using the known volume of standard solution

used the concentration of the unknown can be calculated

Naming Acids and Bases

•What is the name of HCl?• There are two types of acid:•Binary Acid – 2 elements, one of

which must be H• Trinary Acid – 3 elements, one of

which must be H and another O

• Naming a binary acid• Hydro – stem of element – ic acid• HCl hydrochloric acid

• Naming a trinary acid• Stem of element – ic if polyatomic ends in

ate, ous if the polyatomic ends in ite - acid• HNO3 nitric acid
