Method of Analysis Titration
Add 50ml anhydrous ethanol into 250ml conical bottle, 2 drops of phenolphthalei indicator, use 0.1mol/L NaOH to mark the drops to slightly red, use an analytical balance to weigh 0.2500g sample (M sample), cool it with ice-salt water to below 0 degrees, and then use 0.1mol/L NaOH to mark the drops to slightly red. Note that V(NaOH) is consumed at this time, and make a blank V(blank).
Calculate formula:
0.1mol/L NaOH × [V(NaOH) -V(blank)]× 0.16017/ M 100%
Package: Fluorinated bottle, 25kg/drum, or according to customer's requirement.
