Acidic and Basic Salts

Acidic and Basic Salts : 

Acidic and Basic Salts

Salts and Buffers : 

Salts and Buffers Salt is not always NaCl Table salt

Different kinds of Salts : 

Different kinds of Salts Neutral salt Produced from strong acid + strong base Acidic salt Produced from strong acid + weak base Basic salt Produced from weak acid and strong base

Strong Acids / Strong Bases : 

Strong Acids / Strong Bases HCl HBr HI HNO3 HClO4 H2SO4 LiOH NaOH KOH Ca(OH)2 Sr(OH)2 Ba(OH)2 Mg(OH)2

Neutralization Reactions : 

Neutralization Reactions Strong Acid + Strong Base  Water + A Salt HCl + NaOH  H2O + NaCl NaCl is a neutral salt No more reaction takes place.

Neutralization Reactions : 

Neutralization Reactions Strong Acid + Weak Base  A Salt H+ Cl- + NH3  NH4+ Cl- NH4Cl is an acidic salt NH4+  NH3 + H+

Neutralization Reactions : 

Neutralization Reactions Weak Acid + Strong Base  A Salt + Water HClO + NaOH  NaClO + H2O NaClO is a basic salt ClO- + H2O  HClO + OH-

Neutralization Reactions : 

Neutralization Reactions Weak Acid + Weak Base  A Salt HClO + NH3  NH4ClO NH4ClO (aq) could be basic or acidic, depending on which is stronger, the acid or the base. (cannot determine!)

Buffers : 

Buffers Solutions that resist change in pH when a small amount of an acid or base is added

Buffers : 

Buffers Buffers contain particles that react with H+ and particles that react with OH-. Mix a weak acid with one of its basic salts Mix a weak base with one of its acidic salts Ingredients 100% PURE SQUEEZED PASTEURIZED ORANGE JUICE, ACID REDUCED ORANGE JUICE, CALCIUM CITRATE*, ASCORBIC ACID (VITAMIN C)*, AND BETA-CAROTENE*. *INGREDIENT NOT FOUND IN REGULAR ORANGE JUICE

Uses of Buffers :
