3) You are provided with a 4.500 M HCl solution and you are tasked with making...
How would you prepare 10 mL of a 0.25 M HCl solution if 1 M HCl was available?How much 1 M HCl is needed? How much distilled water is used?
how much HCL is needed? please show calculations Prepare 500 mL of a 0.1 M HCl (conc. HCl stock is approx. 12.1 M) solution by diluting the appropriate quantity of conc. HCl with distilled water. Show your instructor the calculation before making the solution. Fill your burette with the HCl solution and standardize it against sodium carbonate as follows.
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 7.00×10−2 M HCl, 100 mL of 5.00×10−2 M 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...
Imagine that you are in chemistry lab and need to make 1.00 L of a solution with a pH of 2.50. You have in front of you 100 mL of 7.00×10−2 M HCl, 100 mL of 5.00×10−2 M 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...
Imagine that you are in chemistry lab and need to make 1.00 L of a solution with a pH of 2.80. You have in front of you 100 mL of 7.00×10−2 M HCl, 100 mL of 5.00×10−2 M NaOH, and plenty of distilled water. You start to add HCl to a beaker of water when someone asks you a question.

Imagine that you are in chemistry lab and need to make 1.00 L of a solution with a pH of 2.80. You have in front of you 100 mL of 7.00×10−2mol L−1 HCl, 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...
. You have 27.0 mL of a 1.500 M stock solution of HCl that must be diluted to 0.650 M. How much water (in mL) should be added?
4 June 2019 CHEM 177-Su19 Chapter 4 APP-1 4. Hydrochloric acid (HCI) is generally sold as an 11.65 M solution. When doing titration experiments, many will use an HCl concentration of 1.00 M HCl. If you wanted to make 150 mL of 1.00 M HCI, how many mL of the stock HCl solution would you need? 5. A 4.00 L stock solution of H3PO4 of unknown concentration was mixed with 4.00 L of pure water. The concentration of the new...
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 6.00×10−2 M HCl, 100 mL of 5.00×10−2 M 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...
please explain how the pH was gotten.. especially the 10^-2.7 how do i put that in my calculator Part A Imagine that you are in chemistry lab and need to make 1.00 L, of a solution with a pH of 2.70 Assuming the final solution will be diluted to 1.00L how much more HCl should you add to achieve the desired pH? Express your answer to three significant figures and include the appropriate units. You have in frort of you...
