What is ka for HNO2(aq) H plus (aq) plus NO2-(aq)?

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.


What is Ka for HCN(aq) H plus (aq) plus CN and ndash(aq)?

HCN(aq) ==> H^+(aq) + CN^-(aq)Ka = [H+][CN-]/[HCN] and the value can be looked up in a book or on line.


What is Ka for H2CO3(aq)H plus (aq) plus HCO3-(aq))?

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.


What is the chemical equation for the neutralization of nitrous acid with magnesium hydroxide?

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


What is Ka for H3BO3aq H aq H2BO3-aq?

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.
