Chemistry

Imagine that you are in chemistry lab and need to make 1.00 L ofa solution with a pH of 2.80. You have in front of you 100 mL of7.00×10−2 M HCl, 100 mL of 5.00×10−2 M NaOH, and plenty ofdistilled water. You start to add HCl to a beaker of water whensomeone asks you a question. When you return to your dilution, youaccidentally grab the wrong cylinder and add some NaOH. Once yourealize your error, you assess the situation. You have 82.0 mL ofHCl and 86.0 mL of NaOH left in their original containers.

Assuming the final solution will be diluted to 1.00 L , how muchmore HCl should you add to achieve the desired pH?
