A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. When strong acids or strong bases are added, buffers either accept protons when they are in excess or donate protons when they have been depleted to minimize changes in pH. Which of the statements correctly describe the properties of a buffer?

口The conjugate base of an acidic buffer will accept hydrogen protons when a strong acid is added to the solution.
An acidic buffer solution is a mixture of a weak acid and its conjugate base.
An acidic buffer solution is a mixture of a weak base and its conjugate acid.
The weak acid of an acidic buffer will accept hydrogen protons when a strong base is added to the solution.
The weak acid of an acidic buffer will donate hydrogen protons when a strong base is added to the solution.
The conjugate base of an acidic buffer will donate hydrogen protons when a strong acid is added to the solution.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
