1. A comic book villain is holding you at gun point and is making you drink a sample of acid. She gives you a beaker with 100ml of a strong acid with pH=5. She also gives you a beaker of a strong base with a pH=10. You can add as much of the strong base to the strong acid as you want, and you must then drink the solution. You'd be best off trying to make the solution neutral before...
Calculate and plot this titration curve with the following information: 50mL 0.1M acetic acid with 0.1M NaOH from 0-60 mL in 1 mL steps. Thanks!
50.00 mLof 0.1M NaOH solution is titrated with 0.05M H2SO4solution. Calculate the volume of the H2SO4 solution that is required to completely neutralize the NaOH solution. Leave your answer in 4 significant fIgures.
Which do you think is a better buffer (more resistant to addition of acid and base)? a solution that is 0.1M in HA and 0.01M in A a solution that is 0.01M in HA and 0.1M in A a solution that is 0.1M in HA and 0.1M in A a solution that is 0.05M in HA and 0.05M in A
