At the equivalence point for a weak acid-strong base titration an equal number of moles of OH- and H+ have reacted, producing a solution of water and salt. What affects the pH at the equivalence point for a weak-acid/strong-base titration? The basicity of the salt anion The auto-ionization of water None of these The acidity of the salt cation

What happens when light is scattered?

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light
