Materials
-citric acid (sour keys)
-plastic dish
-weighing scale
-big beaker
-3 small beaker
-scoopula
-titration device
-sodium hydroxide
-phenolphthalein
-stand and clamp
-heater
Procedure
– 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
Analysis:
The internet said that the pH of Citric acid is 3.2
When we did our calculations we got 2.14.
