Application of Color Variation to Impatiens balsamina L. As An Environmentally friendly acid-base Indicator
An acid-base titration is one of the quantitative analysis methods involving a high-polluting, harmful, hazardous, and relatively expensive synthetic indicator. The development of the concept of green chemistry encourages research to invent natural indicators that are more environmentally friendly....

An acid-base titration is one of the quantitative analysis methods involving a high-polluting, harmful, hazardous, and relatively expensive synthetic indicator. The development of the concept of green chemistry encourages research to invent natural indicators that are more environmentally friendly. Impatiens balsamina L. flower has a variety of colors and contains anthocyanin pigments. Rose pink, red, violet, orangish red, and pink Impatiens balsamina L. flower were extracted with acidified ethanol solvent. All five I. balsamina L. flower extracts indicate discoloration on pH range 10-12. Violet flower extract has an error percentage of strong acid-strong base titration which was 50.48 ± 2.18%, while in strong acid-weak base titration was 19.27 ± 1.15%. Meanwhile, it cannot be applied in weak acids-strong base titration. Thus, I. balsamina L. flowers can be used as an alternative to environment-friendly natural acid-base indicators. |
