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

 H2SO4       +    NaOH         Na2SO4      +     H2O

If 43.2 mL of 0.236 M NaOH reacts with 36.7 mL of H2SO4, what is the concentration of the H2SO4 solution? answer



2. Given the following equation:

  NaOH   +   HCl    H2O    +   NaCl

If 36.7 mL of HCl solution is needed to react with 43.2 mL of a 0.236 M NaOH, what is the concentration of the HCl solution? answer



3. Given the following equation:

Al(OH)3    +   HCl         AlCl3    +    H2O

How many mL of 1.2 M HCl is needed to dissolve 5.8 g of Al(OH)3? answer



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