Predict whether each of the following salt solutions will be A) acidic, B) basic, or C) neutral. Remember that
ionic compounds dissociate completely in water.
Ka for HNO₂ = 4.0 × 10⁻⁴ Kb for NH₃ = 1.8 × 10⁻⁵
H₃PO4: Ka1 = 7.5 × 10⁻³ Ka₂ = 6.2 × 10⁻⁸ Ka₃ = 4.8 × 10⁻¹³
a. NaCl (aq)
b. NH₄NO₃ (aq)
c. NaCH₃CO₂ (aq)
