CHEMISTRY Chapter 15 Applications of Aqueous Equilibria

CHEMISTRY Chapter 15 Applications of Aqueous Equilibria. Two important points: Reactions with strong acids or strong bases go to completion. Reactions with only weak acids and bases reach an equilibrium. The pH scale. The pH scale ranges from 0 to 14. Acids have a pH less than 7.

Isolation of natural acid base indicator from the flower sap of Hibiscus rosa sinensis

Hibiscus rosa sinensis is a species of family Malvaceae. Indicators are very special chemicals, they change colour of the solution with change in Ph by adding acid or alkali. In the present work acid base titration has been performed by using natural indicators. The natural indicator is prepared from the most commonly occurring flower Hibiscus rosa sinensis . Aqueous and methanolic extract of flower were used as natural indicator. Two acids (H2SO4 and CH3COOH) and two bases (KOH and NH4OH) were selected for acid base titration. 1.0N, 0.1N and 0.5N strength of these acids and bases were prepared. The results obtained by the natural indicators are almost similar to the results given by the synthetic indicator. Thus natural indicators from flowers can be used for acid base titration at any dilution. Titration with aqueous extract of natural indicator has not yet been done by any research team. Using aqueous extract of flower as indicator is more economical and with the same accuracy of result as that given by synthetic indicator.
