Acid-Base Buffers Worksheet
la) The combination of HBr and NaCIO4
cannot be used to form a buffer. (T or F)
b) If the logarithmic term in the Henderson-
Hasselbalch equation is = 0, then is the acid
concentration greater, less than or equal to
the base concentration?
c) When a strong base is added to a buffer
solution, the pH will decrease but only
slightly. (T or F)
d) If you start with 50.0 mL of 0.20 M
C6H5ONA, how many mL of 0.40 M HBr do
you need to add to make a buffer of C6H5OH
/ C6H5ONA? Record your answer with 2 digits
after the decimal point.
