A buffer solution contains 0.303 M C6H5NH3Cl and 0.424 M C6H5NH2 (aniline). Determine the pH change when 0.108 mol HClO4 is added to 1.00 L of the buffer. pH after addition − pH before addition = pH change =

If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster
