Full Range Indicator, pH Range 1-13

A Full Range pH Indicator is a chemical solution or test medium (like paper or liquid) that visually displays the acidity or alkalinity of a substance across a wide pH range, typically from pH 1 to 13. It changes color depending on the pH of the solution it contacts, offering a quick, general estimate of pH.

• pH Range:

  • 1 to 13 (full spectrum of acidity to alkalinity)

• Form:

  • Available as liquid solution, test strips, or paper rolls

• Color Scale:

  • Multi-color chart indicating pH changes typically in 1-unit increments

• Composition:

  • Contains a mixture of pH-sensitive dyes, such as methyl red, bromothymol blue, and phenolphthalein

• Packaging:

  • Dropper bottles (10–500 mL), booklets, or reels of test paper

• Storage Conditions:

  • Store in a cool, dry place away from direct sunlight
