Calculate the pH of a solution that contains 1 00 M HCN (K a 6 2 10 10 ) and 5 00 M HNO 2 (K a 4 0 10 4 ) Also calculate the concentration of cyanide ion (CN ) in this solution at equilibrium ...

Since HCN and HNO are both weak acids and are thus primar ily undissociated the major species in the solution are HCN HNO2 and HO All three components ...

Calculate the pH of a solution that contains 1.00 M HCN (K a = 6.2 10

Question:

Calculate the pH of a solution that contains 1.00 M HCN (K_a = 6.2 × 10^–10) and 5.00 M HNO₂ (K_a = 4.0 × 10^–4). Also calculate the concentration of cyanide ion (CN^–) in this solution at equilibrium.
