What is the acid dissociation reaction for HF dissolving in water?

HF + H2O $$\leftrightarrow$$ F - + H 3 O +

HF + H2O $$\leftrightarrow$$ F + H 3 O

HF + H2O $$\leftrightarrow$$ H 2 F + + OH -

Write the Ka expression for the following reaction: HCN(aq) + H 2 O(l) $$\leftrightarrow$$ CN - (aq) + H 3 O + (aq)

Ka = [HCN][H 2 O] / [CN - ][H 3 O + ]

Ka = [CN - ][H 3 O + ] / [HCN][H 2 O]

Write the acid dissociation expression, Ka, for this reaction: H 3 BO 3 (aq) + H 2 O (l) ↔ H 2 BO 3 - (aq) + H 3 O + (aq)

Ka = $$\frac{\left[H_2BO_3^-\right]\left[H_3O^+\right]}{\left[H_3BO_3\right]}$$

Ka = $$\frac{\left[H_2BO_3^-\right]\left[H_3O^+\right]}{\left[H_3BO_3\right]\left[H_2O\right]}$$

Ka = $$\frac{\left[H_3BO_3\right]}{\left[H_2BO_3^-\right]\left[H_3O^+\right]}$$

Ka = $$\frac{\left[H_3BO_3\right]\left[H_2O\right]}{\left[H_2BO_3^-\right]\left[H_3O^+\right]}$$

[H 3 BO 3 ][H 2 O] = [B 2 BO 3 - ][H 3 O + ]

Write the acid dissociation expression, Ka, for this reaction: HClO 2 (aq) + H 2 O (l) ↔ ClO 2 - (aq) + H 3 O + (aq)

Ka = $$\frac{\left[ClO_2^-\right]\left[H_3O^+\right]}{\left[HClO_2\right]}$$

Ka = $$\frac{\left[ClO_2^-\right]\left[H_3O^+\right]}{\left[HClO_2\right]\left[H_2O\right]}$$

Ka = $$\frac{\left[HClO_2\right]}{\left[ClO_2^-\right]\left[H_3O^+\right]}$$

Ka = $$\frac{\left[HClO_2\right]\left[H_2O\right]}{\left[ClO_2^-\right]\left[H_3O^+\right]}$$

[HClO 2 ][H 2 O] = [ClO 2 - ][H 3 O + ]

Write the acid dissociation expression, Ka, for this reaction: HCl (aq) + H 2 O (l) → Cl - (aq) + H 3 O + (aq)

Ka = $$\frac{\left[Cl^-\right]\left[H_3O^+\right]}{\left[HCl\right]}$$

Ka = $$\frac{\left[Cl^-\right]\left[H_3O^+\right]}{\left[HCl\right]\left[H_2O\right]}$$

Ka = $$\frac{\left[HCl\right]}{\left[Cl^-\right]\left[H_3O^+\right]}$$

Ka = $$\frac{\left[HCl\right]\left[H_2O\right]}{\left[Cl^-\right]\left[H_3O^+\right]}$$

[HCl][H 2 O] = [Cl - ][H 3 O + ]
