How many moles of HCl need to be added to 200.0 mL of a 0.200 M solution of NaF to make a buffer with a pH of 3.60? (Ka for HF is 6.8 x 10-4)
1)A 25.0-mL sample of 0.130 M HCl is mixed with 15.0 mL of 0.240 M of NaOH. The pH of the resulting solution will be nearest [Suggestions: use an I-C-E table to solve this problem. Don't forget to use the TOTAL volume when calculating H+ (or OH-) concentration. 2)In the titration of 50.0 mL of 0.100 M benzoic acid (a monoprotic acid) with 50.0 mL of 0.100 M Na0H, the properties of the solution at the equivalence point will correspond...

Determine the pH of a solution of 1 mL of HCl in 2L of water. The density of HCl is 1.2 g/mL
QUESTION 24 136 ml of 0.480 M HCl solution is mixed with 136 ml of 0.240 M Ba(OH)2 solution in a coffee cup calorimeter of negligible heat capacity. The initial temperature of the two solutions are both at 20.00 degrees C. The the final temperature of the combined solution is 23.20 degrees C. cof H 20 - 4.184 J/g °C;d of solution is 1.00g/ml. Refer to the following: Ba(OH)2 + 2HCI --> BaCl2 + 2 H20 (answers are rounded to...
ACIDS AND BASES Calculating the pH at equivalence of a titration A chemist titrates 200.0 mL of a 0.5694 M sodium hydroxide (NaOH) solution with 0.6230 M HCl solution at 25 °C. Calculate the pH at equivalence. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HCl solution added. PH-0 5 ?
