2
Sour to taste Turn litmus red Phenolphthalein stays colorless Electrolytes (conduct) React with some metals to form H 2 gas How do we recognize an acid from its formula? What are the pH values for acids?

3
Bitter to taste Slippery to touch Turn litmus blue Phenolphthalein turns MAGENTA!!!!! Electrolytes How do we recognize a base from its formula? What are the pH values for bases?

4
Pouvoir hydrogene: “hydrogen power” pH=measure of [H 3 O + ] (Acidity) [H 3 O + ] expressed in powers of 10 ex: 10 -14 to 10 -1 **Formula for calculation: -log [H 3 O + ] = pH

5
if [H 3 O + ] is: a. 1.00 x 10 -3 M b. 1.00 x 10 -6 M c. 1.00 x 10 -7 M

6
pOH = -log [OH - ] [OH-] x [H 3 O+] = 1 x 10 -14 pH + pOH = 14 So….. If pH is 2, then pOH is 12 If [OH - ] is: a. 1.0 x 10 -5 b. 1.0 x 10 -12

7
What is the pH of HCl solution? What is the pH of NaOH solution? What should the final pH of the solution be? Write the equation for the reaction. Acids and bases neutralize one another. Acid + base salt + water Salt is made of cation from base and anion of acid

8
Complete the virtual titration lab for homework This is the same reaction you did yesterday in lab! Analytical method in which a standard (known concentration) solution is used to determine concentration of another
