What are some characteristics of acids and bases?

pH < 7

pH > 7

Change the color of acid-base indicators.

Bitter Taste

Sour Taste

Electrolytes

Called Alkalines


Rules for naming binary acids h nonmetal
Rules for naming Binary Acids (H+nonmetal)

  • Start with HYDRO~

  • Write the ROOT of the NONMETAL

  • Change the ending to ~IC

  • Add the word ACID

    Example: H2S  hydrosulfuric acid


You try
You try ….

HF 

HCl 

HBr 

Hydroflouric acid

Hydrochloric acid

Hydrobromicacid


Rules for naming ternary acids h polyatomic
Rules for naming Ternary Acids (H+polyatomic)

  • NO HYDRO!!!!!!!!!!

  • Name the POLYATOMIC ION

  • Change the ending;

    • ate  IC

    • ite OUS

  • Add ACID

    Examples H2SO4 sulfuric acid

    H2SO3  sulfurous acid

HNO3

HNO₂ 

H₂CO3 

Nitric acid

Nitrousacid

Carbonicacid


Formulas of acids
Formulas of Acids

Step 1-- The cation will be hydrogen. Write H first+1 charge.

Step 2-- Identify the anion and its charge (nonmetal or polyatomic)

Step 3 --Balance the charges (Use criss-cross method)

Names of bases
Names of Bases

  • Bases are compounds that produce hydroxide ions when dissolved in water.

  • We refer to them as-ALKALINE

  • Ionic compounds that are bases are named like ionic compounds


Naming bases
Naming Bases

  • Name cation (metal)

  • Name the anion (hydroxide)

  • Base Examples

    • NaOH: Sodium Hydroxide

    • LiOH: Lithium Hydroxide

    • KOH: Potassium Hydroxide

    • Ca(OH)2 : Calcium hydroxide
