The document contains data from experiments measuring pH, residue weight, and KOH concentration over time for 3 initial trials. The pH decreases over time for each trial from over 13 to around 12.68. The residue weight increases then decreases over time as the experiments progress. The KOH concentration follows a similar trend to the pH, decreasing slightly for each trial over time.
