please answer all 3 Which of the following aqueous solutions are buffer solutions? (Select all that apply.) O 0.33 M NH,Br + 0.34 M NaBr O 0.17 M NaOH + 0.23 M NaBr O 0.27 M HBr + 0.19 M NaBr O 0.13 M HOCN + 0.20 M NaCN O 0.36 M CH3COOH + 0.26 M CH3 COONA A buffer solution is 0.414 M in HCN and 0.253 M in NaCN. If K, for HCN is 4.0x10-10, what is the pH of this buffer solution? A buffer solution is 0.374 M in H,S and 0.399 M in KHS. If K for H,S is 1.0 x 10, what is the pH of this buffer solution? pH =
