You want to dilute a 6.00 M HCl solution to 3.01 M. You need 500. mL of the diluted solution. How much stock solution (6.00 M HCl) must you use? Give your answer in mL.
You have 659.3 mL of a stock solution 4.660 M HCl. For a particular experiment, your lab partner prepared a diluted solution for you to use. In her notes, you read: " Using a volumetric pipet, took 246.54 mL of stock solution and diluted it to 739.21 ml in a volumetric flask. Then, took 100.00 mL of that solution and diluted it to 194.63 mL in a second volumetric flask. " What is the concentration that you should report for...
A solution of 0.0480 M HCl is used to titrate 27.0 mL of an ammonia solution of unknown concentration. The equivalence point is reached when 15.5 mL HCl solution have been added. (Assume Kw = 1.01× 10-14.) (a) What was the original pH of the ammonia solution? 匹の10.85 (b) What is the pH at the equivalence point? の5.50 (c) Draw a titration curve for this titration. ( r curve should be quantitative; calculate the pH at different points to construct...
