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 Part A • 100 mL of 6.00 x 10-2mol L-' HCI, • 100 mL of 5.00 x 10-2mol L- NaOH, and Assuming the final solution will be diluted to 1.00 L, how much more HCl should you add to achieve the desired pH? Express your answer to three significant figures and include the appropriate units.

Lakes that have been acidified by acid rain can beneutralized by liming, the addition of limestone(CaC03)

Calculate the pH of the glacial acetic acid and the solution you prepared in step 1. Step 1: Glacial acetic acid, the most concentrated CH3COOH you can buy, has a concentration of 17.54 M. Calculate the concentration of CH3COOH is a solution that is prepared by combining 15.0 mL of glacial acetic acid with enough water to make 250-mL of solution. (Please be very detailed when answering the question)

The pH after adding 21.0 mL of 1.0 M NaOH to 25.0 mL of 1.0 M HCl is   0.087   0.16   0.80   1.1

Would the concentration of hydroxide ion in a 0.20 M solution of sodium hydroxide (NaOH) be greater than, less than, or equal to 0.20 M?

A chemist makes a new solution: 1.0L of a solution that is both that is both 0.6 M NH; and 0.8 M NH,CI. What is the pH of the solution after 0.10 mol of NAOH is added? Round your answer to 2 decimal places. There is no change in volume upon addition of NaOH. pH =

please solve both question. each image has different question.

Please don't provide  handwritten solution .....
