About pH Rainbow
This simulation demonstrates the complete pH scale using visual indicators from pH 1 to 14. Students can explore how different substances fall along the acidity-basicity spectrum and understand the logarithmic nature of pH measurement. Universal indicator provides a rainbow of colors from red (strongly acidic) through violet (strongly basic), while red cabbage juice offers a natural alternative with similar color changes.
Understanding pH is essential for chemistry, biology, and environmental science. This virtual laboratory helps students recognize common substances and their pH values, compare natural and synthetic indicators, and grasp the relationship between pH and hydrogen ion concentration in everyday contexts from household cleaners to food preservation.
