pH Lab

-citric acid (sour keys)
-plastic dish
-weighing scale
-big beaker
-3 small beaker
-titration device
-sodium hydroxide
-stand and clamp


– We boiled the candy in water so that it will melt and mix with the water

– We divided the solution up into three beakers and began the titrations

– Once we finished the titrations we calculated how much NaOH we used

Results and Calculations

The internet said that the pH of Citric acid is 3.2
When we did our calculations we got 2.14.
This may have been due to human error.
