Q

Molecular Compounds: Naming

A

The names of molecular compounds include prefixes to indicate the numbers of atoms in the molecular formula
These prefixes are the same ones used for hydrates!

20
Q

How to know when a compound is an acid

A

is an acid if its chemical formula starts with one or more hydrogen atoms and has the aqueous state symbol (aq)

-Water is an exception to this rule!

21
Q

TRUE OR FALSE: Acids act like…molecular compounds until they are dissolved in water

A

TRUE

Once dissolved, they break apart into ions like an ionic compound would!

22
Q

Binary acids

A

If the formula of the acid does NOT include oxygen

23
Q

How to name binary acids:

A

Start with the prefix hydro- and end with -ic acid

24
Q

Oxyacid

A

If the formula does include oxyge

25
Q

How to name an Oxyacid

A

Name is based on the anion, and does NOT start with hydro-

26
Q

How to name an Oxyacid: x + 1

A

Anion name: per______ate

Acid name: per_____ic acid

27
Q

How to name an Oxyacid: x

A

Anion: ____ate

Acid name: ____ic acid

28
Q

How to name an Oxyacid: x – 1

A

Anion name: ____ite

Acid name: ____ous acid

29
Q

How to name an Oxyacid: x – 2

A

Anion name: hypo_____ite

Acid name: hypo_____ous acid
