WebJun 18, 2024 · The conjugate acid of NO − 2 is HNO 2; Ka for HNO 2 can be calculated using the relationship: Ka × Kb = 1.0 × 10 − 14 = Kw Solving for Ka, we get: Ka = Kw Kb = 1.0 × 10 − 14 2.17 × 10 − 11 = 4.6 × 10 − 4 This answer can be verified by finding the Ka for HNO 2 in Table E1 Exercise 16.6.2 WebA conjugate base contains one less H atom and one more - charge than the acid that formed it. Let us take the example of bicarbonate ions reacting with water to create carbonic acid and hydronium ions. HCO₃⁻ + H₂O → H₂CO₃ + OH⁻. base + acid → Conj A + Conj B. We see that HCO₃⁻ becomes H₂CO₃. It has one more H atom and ...
