1. Given the following reaction:                                        (hint: balance the equation first)

 H2SO4       +   2 NaOH    g      Na2SO4      +   2 H2O

If it takes 27.4 mL of 0.768 M NaOH to titrate 16.7 mL of H2SO4, what is the concentration of the H2SO4 solution? 0.630 M H2SO4


2. Given the following equation:

  NaOH   +   HCl  g   H2O    +   NaCl

If 24.5 mL of HCl solution is needed to titrate 33.0 mL of a 0.112 M NaOH, what is the concentration of the HCl solution?   0.151 M HCl


3. Given the following equation:

Ba(OH)2    +   2 HClO4     g     Ba(ClO4)2   +  2 H2O

How many mL of 1.2 M HClO4 is needed to neutralize 5.8 mL of a 0.44 M Ba(OH)2solution?     4.3 mL of 1.2 M HClO4


4. Given the following equation:
H2SO4       +    Na2CO3    g      Na2SO4      +     H2O   +    CO2
Calculate the molarity of the H2SO4 solution if it takes 40.0 mL of H2SO4 to neutralize 46.7 mL of a 0.364 M Na2CO3 solution.   0.425 M H2SO4
