is gravimetric analysis or colourimetry more accurate when it comes to precipitation reactions where only around 6g and 100ml of the products are used?
I'm inclined to think gravimetric analysis would be better. Six grams is measured easily and accurately as is 100 mL. In most cases colorimetric analysis works best for dilute solutions; therefore, any small error in measurement would be magnified when converted to the full six gram sample.
