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

    H2SO4 + 2 NaOH g Na2SO4 + 2 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? 0.139 M H2SO4



    2. Given the following equation:

    NaOH + HCl g 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? 0.278 M HCl



    3. Given the following equation:

    Al(OH)3 + 3 HCl g AlCl3 + 3 H2O

    How many mL of 1.2 M HCl is needed to dissolve 5.8 g of Al(OH)3? 186 mL of 1.2 M HCl



    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 0.364 g of Na2CO3. 0.0859 M H2SO4
