Measuring pH
Indicators, Paper, and Meters pH is a measure of the concentration of hydronium (H3O+) ions in an aqueous solution. It is measured on a negative logarithmic scale from 0 to 14. Acidic solutions are below pH 7, with 0 being the most acidic. Basic solutions are above pH 7, with 14 being the most basic. […]
Silvering Glass
Create Silver-Mirrored Christmas Ornaments with a Redox Reaction Create silver ornaments with your students using a chemical process similar to antique mirroring techniques. In this festive activity, silver is plated onto the interior surface of a glass vial via a redox reaction. In the reaction, dextrose is oxidized to gluconic acid, and silver ions are […]
