Dissolution of Soda-Lime Glass in Beverages

The objective of this experiment was to measure and analyze the effect of various beverages on soda-lime silicate glasses. The beverages included milk, orange juice, and coca-cola. It was hypothesized that these common beverages would have little effect on the glass particles by causing minimal degradation. XRD on our samples revealed that our glass was amorphous. The results of this experiment supported this hypothesis. The pH and weight-loss measurements both changed very little over the course of the experiment, indicating that the soda-lime silicate glasses did not dissolve very much in the beverages nor had much of an effect on them. It is recommended that more beverages be tried with longer time durations to determine the aggregate effect of acidic liquids on glass bottles and whether or not they are safe for drinking.
