Place 8–10 drops of 0.1M HCl in each well in the first column (i.e. in wells A1–H1) or until full. Place 8–10 drops of 0.01M NaOH in each well in the last column (i.e. wells A12–H12) or until full. Your top row is your “stock solution” row, or a place to store chemicals you will need later. ................
