LaMotte BCG MR Indicator Tablets, 100/box, are formulated for use in total alkalinity testing as part of LaMotte's trusted water analysis procedures. Each tablet contains a bromcresol green/methyl red (BCG/MR) indicator blend that produces a clear color transition during titration, making it easier for students and laboratory professionals to identify the testing endpoint accurately.

Total alkalinity is an important water quality parameter because it measures water's ability to resist changes in pH. Understanding alkalinity helps students investigate buffering capacity, chemical equilibrium, acid-base chemistry, and the role of dissolved carbonates and bicarbonates in natural and treated water systems.

The convenient tablet format eliminates the need to measure liquid indicators, providing consistent reagent amounts for every test while reducing preparation time and improving reproducibility. This makes the tablets especially well suited for classroom laboratories where multiple students perform the same experiment.

BCG MR Indicator Tablets are an excellent resource for inquiry-based STEM education. Students gain valuable laboratory experience by preparing samples, observing color changes, performing titrations, recording quantitative data, and interpreting water quality results. These activities reinforce scientific reasoning while connecting chemistry concepts to real-world environmental applications.

Designed for use with LaMotte Total Alkalinity Test Kits, these indicator tablets deliver dependable performance for classroom demonstrations, laboratory instruction, environmental monitoring, and water quality investigations. The box of 100 tablets provides ample supply for repeated classroom exercises and laboratory sessions.
