Question

Calculate how many moles of NaOh were present in the volume of FA 2 calculated in (b).

Answer 1

FA1 is sulfuric acid
FA2 is sodium hydroxide
FA3 is FA1and distilled water
Titration procedure:
25 mL of FA3 into a flask
Add 5 drops of phenolphthalein into flask
fill burette with FA2
titrate FA3 with FA2 untrial 1
final FA2 volume 16.75
initial FA2 volume 3.40
volume of FA2 used 13.35
trial 2
final FA2 volume 29.70
initial FA2 volume 16.55
volume of FA2 used 13.15til a permanent pale pink

Answer 2

(b) 25.0 mL of FA3 required 13.10 mL of FA2

Answer 3

\(\sf \large Molarity=\dfrac{moles}{L_{solution}}\)
