Methyl Red, with the chemical formula C15H15N3O2, is a vibrant maroon red crystal azo dye. It serves as a widely used pH indicator in laboratory settings. When dissolved in water, it forms a soluble solution that finds applications in various chemical and microbiological experiments. To prepare a 0.2% methyl red solution, 0.2 grams of methyl red is dissolved in 100 milliliters of solvent, typically water or ethanol. The color of methyl red changes from red in acidic solutions (pH < 4.4) to yellow in neutral to basic solutions (pH > 6.2). This 0.2% methyl red solution is highly versatile and dependable for pH measurement, playing a crucial role in microbiological testing. It aids in differentiating bacterial species based on their metabolic processes.
