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.

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 a Ka for H3BO3(aq) H(aq) plus H2BO3(aq)?
The acid dissociation constant (Ka) for the reaction of boric acid (H3BO3) in water can be expressed as: [ H3BO3(aq) \rightleftharpoons H^+(aq) + H2BO3^-(aq) ] The Ka value represents the equilibrium constant for this reaction, indicating the extent to which boric acid donates protons to form hydronium ions (H+) and the borate ion (H2BO3^-). For boric acid, this Ka is relatively small, reflecting its weak acidic nature compared to stronger acids.
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.
