Asolution is prepared by dissolving 0.23 mol of benzoic acid and 0.27 mol of sodium benzoate in water sufficient to yield 1.00 l of solution. the addition of 0.05 mol of naoh to this buffer solution causes the ph to drop slightly. the ph does not decrease drastically because the naoh reacts with the _present in the buffer solution. the ka of benzoic acid is 1.36 x 10-3 a) h20 b) h30+ c) benzoate ion d) benzoic acid e) this is a buffer solution: the ph does not change upon addition of acid or base.

The pH does not decrease drastically because the NaOH reacts with the D) Benzoic acid present in the buffer solution.

Explanation:

The hydroxide ions will react with acidic part of the solutions, it means the benzoic acid, so it will form the conjugate base, the benzoate ion.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
