A burette was filled with 50.00 ml of NaOH ans a titration was performed against an unknown acid dissolved in 100.00 ml of water which also contained 4 drops of phenolphthalein.
Molarity of NaOH solution = 0.0925 M
Initial volume in burette = 0.03 ml
Volume used to reach the endpoint= 23.48 ml Grams of unknown acid used = 0.224 g
pKa of the acid = 4.15
How many moles of NaOH were required in the reaction?
