Which of the following is
 the best conductor of
      electricity?

         NaCl (s)
        NaCl (aq)
       C6H12O6 (s)
       C6H12O6 (aq)
ANSWER

 NaCl (aq)
    Which solution is the best
    conductor of electricity?
 0.1 M HNO3
 0.1 M CH3COOH

 0.1 M C6H12O6

 0.1 M C2H5OH
   What happens to the
conductivity of a solution if
KCl is added to a saturated
     solution of KCl?
In a 0.01 M solution of
HCl, blue litmus will do
        what?
 In the below reaction,
which quantity would be
 considered the proton
         donor?

HF + H2O      H3O+   +   F-
    Pure water is similar to
    1.0 M HCl in that they
            both
 Contain H3O+
 Are neutral to litmus

 Have a pH higher

  than 7
 Are good conductors

  of electricity
   According to the
Bronsted-Lowry theory,
 an acid is any species
     that can . . .
 When tested, a solution turns red
litmus to blue. This indicates that
 the solution contains two types of
ion. Which ion is more abundant?
  What will water
become if it acts as a
      base?
        H3O+
In the reaction below is
water an acid, a base, or
         both?
   H2 O + H 2 O  H3   O +   +   OH -




            BOTH
Which salt will hydrolyze in water to
     create a basic solution?
   NaNO2   What does this mean?
   CaCl2
   BaI2
            React each with water . .
   MgSO4   If the product is a strong
            base and a weak acid, it
            will be a basic solution.
NaNO2 + H2O  NaOH + HNO2
            Note the mole ratio
                   is 2:2
How many mL of 1.0 M H2SO4 are
needed to exactly neutralize 15 mL
        of 2.0 M Ba(OH)2?


           30mL
 As 50mL of 0.1 M HCl
  is added to 100mL of
 0.1M NaOH, the pH of
the NaOH will do what?
    Write a chemical
  equation that would
       represent a
 neutralization reaction.

NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)
A water solution contains 0.50 moles
  of HCl. How many moles KOH
 should be needed to neutralize the
               acid?
          0.50 moles
     How many grams does that represent?

                  28.5g
What is the pH of a solution if
    the HYDROXIDE ion
concentration is 1 x 10-4 moles

          per liter?
              10
What is the [H3 O+]
                  of a
0.001 M HCl solution?


     1.0 x   10 -3 M
 You find an unknown solution in the
                lab

     What characteristics will it have if it is an acid?
BASE:                                         ACID:
pH=↑7                                         pH=↓7
Slippery                                      Sour
Litmus: blue                                  Litmus: red
Pheno: pink                                   Pheno: colorless

Caustic                                       [OH-] ↓ [H+]
[OH-] ↑ [H+]
 What materials will you
need if you are going to do
 titration to see what the
   concentration of the
        chemical is?
Burets, beakers, acid and base (one with
an unknown concentration),
phenolphthalein, Erlenmeyer flask
