Section 1: Multiple Choice questions


#1 Which of the following definitions matches the term?

pH + pOH =



#2 Which of the following definitions matches the term?

strong acid-weak base reaction



#3 Which of the following terms matches the definition?

increasing/decreasing concentrations of buffer components, but keeping the ratios constant (if you don't it'll change the buffer capacity for either acid or base respectively)



#4 Which of the following terms matches the definition?

HA(aq) + OH- --> A-(aq) + H2O(L) if weak acid is in excess --> a buffer --> Hendeson Hasselbalch equaiton if strong base is in excess, the moles of excess hydroxide ions is used for pH if acid and base are equimolar then the equilibrium concentr



#5 Which of the following terms matches the definition?

pH = pKa



Section 2: True/false questions


#6 Determine if the following combination is true or false.

strong acid strong base equivalence point

pH = 7 @ 25 C / 298 K







#7 Determine if the following combination is true or false.

how do you calculate a buffer's pH

14 always!!







#8 Determine if the following combination is true or false.

in what range are buffers effective

7, could be acid (pH) or base (pOH)







#9 Determine if the following combination is true or false.

what is a buffer

if weak base is in excess --> a buffer --> Hendeson Hasselbalch equaiton if strong acid is in excess, the moles of excess acid are used to determine pH if acid and base are equimolar then the equilibrium concentrations are used to determine pH







#10 Determine if the following combination is true or false.

H2O pH is always...

7, could be acid (pH) or base (pOH)
