Using 12-wells strips, different amounts of equimolar solutions are mixed. The volume of solid produced is observed. The maximum volume of solid is produced when the ratio of the combining volumes equals the ratio of coefficients from the balanced chemical equation. The chemicals are toxic. The alternative chemicals are less toxic.
Trisodium phosphate is sufficiently basic to corrode eye tissue.
Go to Top Precautions Do not ingest the chemicals. Wear eye protection. All solutions are 0.1 M solutions. Add 4 drops of distilled water to each of 8 wells in a clean 12-well strip. End by adding 8 drops of potassium iodide to the 8th well.
