Naming and Properties of Sulfur Acids

The video tutorial explains how to name the compound H2SO3 using a flowchart. It begins by identifying the elements and their charges, leading to the recognition of SO3 as the sulfite ion. The naming process involves modifying the stem of 'sulfite' to 'sulfurous acid', considering exceptions in chemistry, particularly with sulfur-containing compounds. The tutorial emphasizes the importance of understanding these exceptions for accurate chemical naming.

• Sulfate

What suffix is used when naming acids derived from ions ending in 'ite'?

• -ide

• -ic

• -ous

• -ate

What is the correct name for H2SO3 according to the flowchart?

• Sulfuric acid
