A pH indicator solution is a chemical analyst’s key to success. Using a small amount of chemical indicator, an analyst can visually determine the pH of an acidic or basic solution. In most cases, the indicator triggers a color change, with the result of this color change revealing the pH of the solution.
Indicator solutions have a variety of applications in bio and analytical chemistry. Whether you are practicing titration in the laboratory or gauging the outcome of a chemical reaction, these solutions can tell you a lot about what you’re observing. While reading pH indicators does introduce the possibility of human error, laboratory indicators can provide great insight into the likely pH range.
