Answer:
e) pH is independent of concentration.
Explanation:
a) It is a mixture of a weak acid and its conjugate base. <em>TRUE. </em>A buffer is defined as a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.
b) Resists pH changes because it reacts with added acid or base. <em>TRUE. </em>Thermodynamically, the reaction of added acid or base is faster with the buffer mixture than with H⁺ or OH⁻ ions of the solutions.
c) The maximum buffer capacity is at pH = pKa. <em>TRUE. </em>The buffer capacity is pka±1. For this, buffer capacity is maximum in pka.
d) pH is dependent on the solution ionic strength and temperature. <em>TRUE.</em> Ionic strength and temperature are factors that influence concentrations of ions in solutions as the H⁺ ion that is the responsible
e) pH is independent of concentration. <em>FALSE. </em>pH in a buffer depends completely of concentrations of the acid and its conjugate base or vice versa.

Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.
Explanation:
The energy of a wave is given by the formula;
E= hf
Whereby;
E = energy
h = Plank’s constant
f = frequency
Remember that f can be also represented as;
¹/ λ
Whereby;
λ = wavelength
Wavelength and frequency are therefore inversely proportional.
Decreasing the wavelength increases the frequency of a wave and vice versa, as long as the energy of the wave remains constant.
