+ Concentrations

1. To represent the concentration or molarity of a substance put _____________ around the substance.

E.g., the concentration of H+ ions can be represented as [H+].

+ Neutral Solutions

2. A solution with equal _____________ and ______________ is neutral.

3. A ________________________ is an experiment where one creates a solution with equal moles of H+ atoms and OH- atoms.

+ Titration in a Lab

A. Put ________________ in your solution makes sure it’s acidic.

B. Slowly add a base until the indicator tells its _____________ and turns green.

+4. To read a Buret look at the

bottom of the ___________________.

5. To determine the amount of a solution added subtract the ____________ reading from the _____________ reading.

Reading a Buret

+If I fill up a Buret starting at

0mL of acid and its final reading is 34 mL, then how

much acid have I added?

Reading a Buret

+If I fill up a Buret with 20mL of base and its final reading is 45mL, then how much acid

have I added?

Reading a Buret

+6. Because you trying to make

the concentrations and volumes equal to each other use the equation ______________________.

Reading a Buret

+You have to adjust to the

formula

H2SO4 + 2KOH K2SO4 + 2H2O
