Received 21 Jan Accepted 21 Mar Published 10 Apr Abstract Commonly used indicators for acid-base titrations are synthetic, and this work was focused to identify the eco-friendly natural indicators and to determine their pKa values.

Introduction Titration is the most common laboratory method of quantitative chemical analysis that is used to determine the concentration of analyte. Materials and Methods 2. Acid-Base Titrations Three types of titrations such as strong acid-strong base, strong acid-weak base, and weak acid-strong base were carried out using flower extracts as indicators, and their accuracy were compared with commercially available synthetic indicators such as methyl orange, methyl red, and phenolphthalein.

I feel it is much better than Perkin's Mauve. Before I ruin a large amount of cloth trying to color them with these dyes, I want to know more about their properties.

The Questions Brother Gregory wants you to investigate the properties of various colored dyes. He has discovered that all of the samples given to him by Herr Grunewald change color when exposed to different hydrogen ion concentrations. He wants you to - find out the relationship between hydrogen ion concentration and pH, and find out what colors the dyes turn in different hydrogen ion concentrations.

Tools of the Trade To carry out this investigation you must first determine the relationship between hydrogen ion concentration and the pH of the liquid or solution.

Hydronium ion - in solutions in water, hydrogen ions combine with water molecules to form a stable, hydronium ion. Typical hydronium ion concentrations are; pure water 1. Note: writing concentrations like this - 10 -2 - is called exponential notation. Hydroxide ion concentration - this value is written [OH - ]. Base - is a compound that furnishes hydroxide ions OH - , to a solution in water.

Indicator - a chemical dye that changes color depending on the hydrogen ion or hydroxide ion concentration in the same solution. Litmus, for example, is blue in a basic solution high hydroxide ion concentration and red in acidic solution high hydrogen ion concentration.
