ka=[H+][NO2_]/[HNO2]
The acid dissociation constant (Ka) for the dissociation of nitrous acid (HNO2) into hydrogen ions (H⁺) and nitrite ions (NO2⁻) can be expressed with the equation: [ K_a = \frac{[H^+][NO_2^-]}{[HNO_2]} ] This equilibrium constant quantifies the strength of HNO2 as an acid; a larger Ka value indicates a stronger acid, meaning it dissociates more completely in solution. For HNO2, the Ka is approximately 4.5 × 10⁻⁴ at 25°C, indicating it is a weak acid.
HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.
The acid dissociation constant (Ka) for carbonic acid (H₂CO₃) dissociating into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻) is a measure of the strength of the acid in solution. The dissociation reaction can be represented as: H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq). The value of Ka for this process is approximately 4.3 x 10⁻⁷ at 25°C, indicating that H₂CO₃ is a weak acid.
Mg(OH)2 + HNO2 -> MgNO2 + H2OI think this equation is beyond me or is an impossible equation. Nitrous acid is a weak acid and the above equation is not correct, so I need to think about it for a while.Mg + NO + H20Possible products, but not sure.Mg(OH)2 + 2HNO2 --> 2H2O + Mg(NO2)2------------------------------------------------------------this may do
The dissociation of boric acid (H₃BO₃) in aqueous solution involves the formation of the borate ion (H₂BO₃⁻) and a proton (H⁺). The acid dissociation constant (Ka) for this reaction is typically around 5.8 x 10⁻¹⁰ at 25°C. This indicates that boric acid is a weak acid, as it does not completely dissociate in water.
Ka= [H+][NO2-] [HNO2]
The Ka for the dissociation of HNO2 is 4.5 x 10^-4. This value represents the equilibrium constant for the reaction of HNO2 dissociating into H+ and NO2-.
The acid dissociation constant (Ka) for the dissociation of nitrous acid (HNO2) into hydrogen ions (H⁺) and nitrite ions (NO2⁻) can be expressed with the equation: [ K_a = \frac{[H^+][NO_2^-]}{[HNO_2]} ] This equilibrium constant quantifies the strength of HNO2 as an acid; a larger Ka value indicates a stronger acid, meaning it dissociates more completely in solution. For HNO2, the Ka is approximately 4.5 × 10⁻⁴ at 25°C, indicating it is a weak acid.

The reaction between calcium hydroxide and nitrous acid (HNO2) would result in the formation of calcium nitrite [Ca(NO2)2] and water (H2O). The balanced chemical equation for this reaction is: Ca(OH)2 + 2HNO2 → Ca(NO2)2 + 2H2O
Since H3PO4 has 3 ionizable hydrogens, it will have three Ka values. Approximate values areKa1 = 7x10^-3; Ka2 = 6x10^-8 and Ka3 = 4.5x10^-13
The chemical equation for nitrous acid is HNO2. The equilibrium expression for its ionization is: HNO2 ⇌ H+ + NO2- with Ka = [H+][NO2-]/[HNO2] = 4.5x10^-4.
