*Titrations
*Allow you to solve for the unknown

concentration of an acid or base using the principles of neutralization reactions

*Let’s stroll through Chem Honors
Memory Lane…

What are Titrations




The process of adding just enough acid or base to neutralize the solution
Remember that acids and bases react with each other to make a neutral salt solution.
• In the following examples, label the acid, base,

1.

and salt.
HCl(aq) + NaOH(aq)

(Acid)

2.



(Base)

Ca(OH)2(aq) + 2HNO3(aq) 
(Base)

(Acid)

H2O(l)
(Water)

+

NaCl(aq)
(Salt)

Ca(NO3)2(aq) + 2H2O(l)
(Salt)

(Water)

BIG IDEA I


To completely neutralize, the acid and base must react in the right ratio.

• What on earth does that mean?
Answer: We need the same amount of H+ ions and OHions in solution so they can form pure water (HOH).
• Why do we need the right amount?
Answer: Need [H+]= [OH-] to form pure water.
 Having more H+ ions leftover would make the solution more acidic  Having more OH- ions leftover would make the solution more basic.  Thus neither of the 2 solutions above would be neutralized.

BIG IDEA II


Finds concentrations of acids or bases that are unknown using math
• Huge for safety in a laboratory among

other uses

Indicators


Used as an acid/base detector during the experiment



Turns color based on what pH level it’s inside of



Many different indicators
• Why?

Answer: It depends on what type of acid and base are being added together.
 Strong acid with strong base neutralizes at a pH of 7
 Weak acid with a strong base neutralizes at a pH around 8.5.

*In Class Demo/ Example
Concentration of Known Soln

Volume of known concentration Volume of unknown soln

*So how is AP Chem
*Titrations can occur with:

different?

*Acid-base Reactions
*Precipitate Reactions
*Oxidation-Reduction Reactions
*We can

fundamental units of matter. [ ] 3. What did Democritus’ proposals lack in explanatory reasoning? Why? They lacked experimental support. [ ] 4. Who essentially continued the work of Democritus with the use of experimental proof? John Dalton. Based on his experimental work he was able to conclude the following hypothesis (also known as Dalton’s Atomic Theory): “1. All elements are composed of submicroscopic indivisible particles (atoms!) 2. Atoms of the same element are identical. 3. Atoms of different…
