Homework Help: CHEM HELPP!!!

Posted by Ashley on Tuesday, March 10, 2009 at 3:38am.

Imagine that you are in chemistry lab and need to make 1.00 of a solution with a pH of 2.50.
You have in front of you

100 of 7.0010−2 , HCL
100 of 5.0010−2 , and NaOH
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 81.0 ml of HCl and 90.0ml of NaOH left in their original containers.

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