          	household ammonia  or NH3(aq)
          	
          	(The base, highest pH)
          	
          	66 Explain, in terms of the pH range for color change on Reference Table M, why litmus is not appropriate to differentiate the acidity levels of tomato juice and vinegar. [1]

          	Litmus is red for all pH values below 5.5.
          	
          	67 Based on the measured pH values, identify the liquid tested that is 10 times more acidic than vinegar. [1]

          	lemon juice
          	
          	There is one zero in 10, so the pH is more acidic (a lower pH) by 1 pH unit.
