   16 Ιαν 2023 · the degree of dissociation can be used to fill out an ICE table. If the reaction is started with n moles of A, and a is the fraction of A molecules that dissociate, the ICE table will look as follows. The mole fractions of A and B can then be expressed by. χA = n(1 − α) n(1 − α) + 2nα = 1 − α 1 + α χB = 2α 1 + α.

   15 Απρ 2024 · Calculate the pH of a solution of a weak monoprotic weak acid or base, employing the "five-percent rule" to determine if the approximation 2-4 is justified. Predict whether an aqueous solution of a salt will be acidic or alkaline, and explain why by writing an appropriate equation.

   The amount of dissociated substance can be determined by counting complete sets of products of dissociation. When we calculate the degree of dissociation, it is essential that we use the total amount of substance (dissociated and undissociated) when we perform the division. Degrees of dissociation are always in the range of 0 to 1.

   Solution: 1) Calculate the [H +] from the pH: [H +] = 10¯ pH = 10¯ 2.876 = 1.33 x 10¯ 3 M. 2) From the 1:1 stoichiometry of the chemical equation, we know that the acetate ion concentration, [Ac¯] equals the [H +]. Therefore, [Ac¯] = 1.33 x 10¯ 3 M. 3) We need to determine [HAc], the acetic acid concentration.
