Calculate the H30+ concentration for each pH: a) pH =12 [H30+] = b) pH = 3[H3o+]

Question

Calculate the H30+ concentration for each pH: a) pH =12 [H30+] = b) pH = 3[H3o+]= c) pH = 5[H30 +]= Which pair of compounds will form a buffer in aqueous solution? HCN and HCI HCI and NaOH HCI and NaCI NaCN and NaOH HCN and NaCN NaCN and KCN In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, or weak bases. Strong acid Weak acid Strong base Weak base Which pair of compounds will form a buffer in aqueous solution? HCN and HCI HCI and NaOH HCI and NaCI NaCN and NaOH HCN and NaCN NaCN and KCN In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, or weak bases. Strong acid Weak acid Strong base Weak base

Explanation / Answer

a) 10^-12

b) 10^-3

c) 10^-5

NaCN and NaOH will form buffer.

Strong Acid = HNO3, H3PO4

Weak Acid= HI, HCN

Strong Base = Ba(OH)2, LiOH

Weak Base = NH3
