Question
Imagine that you are in chemistry lab and need to
make 1.00 L of a solution with a pH of 2.40.
You have in front of you
• 100 mL of 6.00 × 10-²mol L-1
HCI,
• 100 mL of 5.00 × 10-²mol L-1
NaOH, and
• plenty of distilled water.
You start to add HCl to a beaker of water when
someone asks you a question. When you return to
your dilution, you accidentally grab the wrong
cylinder and add some NaOH. Once you realize
your error, you assess the situation. You have 80.0
mL of HCl and 85.0 mL of NaOH left in their
original containers.
