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 Ka for H2CO3aq H aq HCO3aq?

The equilibrium constant ( K_a ) for the dissociation of carbonic acid (H₂CO₃) into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻) can be represented by the equation: [ H_2CO_3 (aq) \rightleftharpoons H^+ (aq) + HCO_3^- (aq) ] The value of ( K_a ) for this reaction at 25°C is approximately ( 4.3 \times 10^{-7} ). This indicates that carbonic acid is a weak acid, as it does not completely dissociate in solution.

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.
