HL Acids & Bases
See pages 162 - 165
Acidic, Basic, or Neutral? Where did these species come from?
Small highly charged ion
See Fig 16 p.167
Aluminum Hexahydrate is amphoteric!
The Bicarbonate blood buffering system
How would you make this buffer? See p.168
Titration of a
Titration of a buffer
Buffers can also be made by adding the weak acid to its salt.
Note the location in the body of the conditions? Does the hemoglobin pick up and drop off the oxygen at the right places?
Salts in Solution Mrs. Coyle. Solutions of Salts -Strong Acids and Strong Bases Produce a neutral solution (pH=7) Example: HCl + NaOH NaCl + H 2 O Strong.

Chapter 2: Chemical Basis of Life Part II: Chemical Reactions Acids and Bases Inorganic Substances.
Salts do not contain H+ or OH- and dissociate when dissolved in H2O. ◦ Resulting ions will conduct electricity in the solution (electrolytes) ◦ Salts.
Common Ion Effect Revisited. pH changes due to Common Ion Effect.
1 Chapter 10 Acids and Bases 10.9 Buffers. 2 When an acid or base is added to water, the pH changes drastically. A buffer solution resists a change in.
Acids and Bases pH Scale Marine Biology. Warm Up What is the pH scale? What is the difference between an acid and a base? What is neutral? How are enzymes.
pH and pOH Ionization of water Experiments have shown that pure water ionizes very slightly: 2H 2 O H 3 O + + OH - Measurements show that: [H 3 O +
Chapter 21 Neutralization Neutralization Reactions Salts in Solution.
The water molecule is a polar molecule, meaning it has a partial positive end and partial negative end.
Carboxylic Anhydrides, Esters and Amides. Naming Anhydrides Drop the word acid and say anhydride.

Chapter 8 Acids and Bases
PH. Water & pH H + can split off from H 2 O, leaving OH – if [H + ] = [ - OH], water is neutral if [H + ] > [ - OH], water is acidic if [H + ] < [ - OH],
1 Function of the Conjugate Base The function of the acetate ion C 2 H 3 O 2 is to neutralize added H 3 O +. The acetic acid produced by the neutralization.
Salts in Solution. A salt is composed of a cation (from a base) and an anion (from an acid) Not all salts are neutral – some can be basic, others.
Chemistry – Chapter 19. Properties of Acids and Bases Acidic solutions taste sour Ex: lemon juice Basic solutions taste bitter and feel slippery Ex: soap.
