A laboratory technician wants to prepare a NaOH solution for use in an experiment to completely react it with 250 mL of 0.50 M H2SO4. The volume of NaOH must equal that of H2SO4. The equation for the reaction is given below.

H2SO4 + 2NaOH Na2SO4 + 2H2O

If only 1 L of 10.0 M NaOH solution is available in the laboratory, what would the technician most likely do?

hkmiu · Answer

Get 125 mL of the 10.0 M NaOH solution, and use it.
Get 12.5 mL of the 10.0 M NaOH solution, and dilute it to 1.00 L.
Get 12.5 mL of 10.0 M NaOH solution, and dilute it to 250 mL.
Get 25 mL of the 10.0 M NaOH solution, and dilute it to 250 mL.
