Question

Calculate the pH of the solution to see if it is in an acceptable range (pH between 6 and 8). If not, please suggest what to add (you do not have to calculate how much) to get within the acceptable range. The current volume and concentrations of acids and bases are as follows:

13.57 mL of 0.007213 M NH₄OH

2.39 L of 0.01053 M C₅H₅N

11.56 L of 0.0026567 M N(CH₃)₃

13.27 mL of 0.086031 M NH₃

5.23 L of 0.3119 M CH₃NH₂

813.14 mL of 0.005629 M glycine

3.53 L of 0.003501 M H₃PO₄

45.6 mL of 0.05304 M CH₃COOH

2.15 L of 0.1234 M H₃C₆H₅O₇

348.29 mL of 0.02150 M C₆H₈O₇

896.25 mL of 0.3587 M H₂C₂O₄

1.29 mL of 0.07389 M HNO₂

37.29 mL of 0.02319 M disodium EDTA

2.71 mL of 18.02 M NaOH

3.59 L of 0.1649 M HCl

Answer 1

0 H20 cene, of nittyolt a 0.007213 M. Nl4got I rita + oH] It produces th] Hoody [ot] = 0.00723 M as it is of audity 1 рон е из Сон) pH = 14-poh - 14+ log [ot] = 14+ (-2.1417 & 11, 85 So The solution is basic. You need to add Acids like Hel, Harry to bring it to there 6-8 range GHS No is pyridine which is basic again Ho ="50. + so it produces ott is H2o.

[ests n] = [of] = 0.01053 m Han pH = 14-pot - 14+ log 0.010s3 and pH = 12.02 So the solution is basic and to you need to and aids (Hi, Hron) to bring the ph 6-8. N(CH3), is also a hare 3 me meme H2o Hamez + 5th It producen ott is solution and it is mono andre bare. Me [NCH3)₂ = 6H] = on 26567 pH = 14 - popott - 14+ ległon] = 19+ log d. 26567 A G - 1142 A acids This is het hart you need to add get pH = 6-8. to

6 NHg is also hasiz. s stilong with v erot NH3 + H20 T NH4 + oH so [Nta] = [OH) = 0, 086031 M... Bolo la lokasitas pH = 14-polt = 14+ log 0.08 6031 to date pH = 12.93 So it is hare you need to add ands to bring the pH to inbetween 6 to 8. peroleh
