Question- Imagine that you are in chemistry lab and need to make 1.00L of a solution with a pH of 2.40. You have in front of you 100 mL of 7.00×10 2M HCl, 100 mL of 5.00×10?2M 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 80.0mL of HCl and 85.0mL of NaOH left in their original containers.
