What are some characteristics of acids
and bases?
pH < 7
Produce H+ ion
Sour Taste
Turns Blue Litmus paper
RED
React with active metals to form H2 gas.
pH > 7
Change the color of acid‐
base indicators.
Bitter Taste
Produce
OH‐ ion
React with each other to form salt and water
Turns Red
Litmus paper
BLUE
Feel slippery
Electrolytes
Called Alkalines
Rules for naming Binary Acids
(H+nonmetal)
1.
Start with HYDRO~
2.
Write the ROOT of the NONMETAL
3.
Change the ending to ~IC
4.
Add the word ACID
Example: H2S  hydrosulfuric acid

Rules for naming Ternary Acids
(H+polyatomic)

NO HYDRO!!!!!!!!!!
1.
Name the POLYATOMIC ION
2.
Change the ending;
3.

Formulas of Acids
Step 1-- The cation will be hydrogen.
Write H with +1 charge above
Step 2-- Identify the anion and its
charge (nonmetal or polyatomic)
Step 3 –Criss Cross the charges
