Acid Naming & Formula Writing

Fill in the Blanks

You can recognize an acid because the formula always

Type answer...

Multiple Select

Mark all of the acids in the list

HCl

NaOH

HNO₃

hydrosulfuric acid

nitrogen trihydride

Categories of Acids

Acids may all start the same, but there are 2 types based on what they contain
Binary acids contain a single nonmetal anion
Oxyacids contain a polyatomic anion which has oxygen in the formula
How are they named differently?

Multiple Select

Mark all of the binary acids in the following list

HBr

NaBr

HBrO₂

H₂S

sulfuric acid

Naming Binary Acids

There are not many of these!
Most important thing is to start ONLY these acids with "hydro"
There is ONE WEIRD EXCEPTION! The polyatomic ion cyanide (CN^1-) is named by binary rules because it doesn't have oxygen
HCN = cyanide --> cyanic so hydrocyanic acid

Multiple Choice

What is the correct name of HF?

fluoric acid

hydrofluoric acid

hydrofluorine

hydrogen monofluoride

Writing Formulas for Binary Acids

Ending in "acid" means you start with H in the formula
"hydro" means you only have 1 other nonmetal
Use the "root" in the name to identify the other nonmetal and it's charge
The charge tells you how many hydrogens you need in the formula (there will only ever be 1 of the other thing in the formula)

Multiple Choice

What is the correct formula for hydrophosphoric acid?

H₂P

H₃P

HP₂

HP₃

Naming Oxyacids

You have to determine the polyatomic ion in the formula in order to name these. Everything is based off of that.
Literally write the name of the polyatomic ion.
If it ends in "ate", drop that and add "ic acid".
If it ends in "ite", drop that and add "ous acid".

Multiple Choice

What is the correct name of HClO₃?

hydrochloric acid

chloric acid

chlorous acid

hydrogen chlorine trioxide

Writing Formulas for Oxyacids

Ending in "acid" means you start with H in the formula
NO "hydro" means you have a polyatomic
Use the "root" in the name and "ic" or "ous" to identify the polyatomic and it's charge
The charge tells you how many hydrogens you need in the formula (there will only ever be 1 of the other thing in the formula)

Multiple Choice

What is the correct formula for phosphoric acid?

H₃P

HPO₄

H₃PO₄

H₃PO₃

HPO₄^2-

You clearly need to know your polyatomic ions and have the cheat handy for your homework. Mark all that apply for you.

I have printed out that cheatsheet from the notes last week!

I handwrote out the list of polyatomics from the jam board/notes video

I have made physical flashcards of the highlighted polyatomic ions

I have made/found a Quizlet set of the highlighted polyatomic ions

I have done none of these things
