    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
