Answer:

0.0140 M H₂C₆H₆O₆.

Explanation:

  • We should mention the relation: <em>Ka = α²C,</em>

Where, Ka is the dissociation constant of the acid.

α is the degree of ionization of the acid.

C is the concentration if the acid.

<em>The percent of ionization (α %) = α x 100.</em>

α = √Ka/C

∴ α is inversely proportional to the concentration of the acid.

<em>So, the acid with the lowest concentration has the greatest percent ionization.</em>

Which statement is correct regarding the reaction ?
larisa86 [58]

The true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

<h3>What is true about the given reaction?</h3>

The given reaction shows a reaction between A and B to form CD

The reaction is a reversible reaction.

A reversible reaction is a reaction which can proceed in either of two ways where the reactants can react to form the product and also the products an break down to form the reactants.

In the reaction given, as the concentration of A and b decreases, the concentration of CD increases and vice versa.

At equilibrium, the rate of formation of CD is equal to the the rate of decomposition of CD.

Therefore, the true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

In conclusion, a reaction at equilibrium has the forward and backward reactions occurring at the sane rate.

Which of the following is not a conjugate acid-base pair?
-Dominant- [34]

Answer:

A. H3O+/OH−

Explanation:

A conjugate acid-base pair are a pair of molecules that differ in 1 H⁺

A. The conjugate pair of H₃O⁺ = H₂O not OH⁻

B. The conjugate pair of NH₄⁺ is NH₃

C. The conjugate pair of C₂H₃O₂⁻ is HC₂H₃O₂

D. The conjugate pair of H₂SO₃ is HSO₃⁻

That means right option, that is not a conjugate acid-base pair, is:

<h3>A. H3O+/OH− </h3>
