Glass is a notorious source of metal ion contamination. three glass bottles were crushed and sieved to collect 1 mm pieces. to see how much al3+ could be extracted, 222 ml of a 0.05 m solution of the metal-binding compound edta was stirred with 0.50 g of the 1 mm glass particles in a polyethylene flask. the al content of the solution after 2 months was 5.2 μm. the total al content of the glass, measured after completely dissolving some glass in 48 wt% hf with microwave heating, was 0.80 wt%. what fraction of the al was extracted from the glass by edta? (enter your answer to 5 decimal places.)
