Red Litmus Paper (Johnson-UK) Pkt of 200 Leaves in Kenya
KSh1,500
The Practical Chemistry of Red Litmus Paper
Unlike generic litmus strips that deliver weak or sluggish color shifts, Johnson-UK litmus papers are manufactured using premium-grade, unbuffered cellulose wood fibers infused with natural lichen dyes [Blue Litmus Paper]. This ensures flawless accuracy:
-
- The Alkaline/Base Reaction: When a strip of red litmus paper touches an alkaline or basic solution (pH greater than 7.0), the dye reacts instantly to the hydroxide ions, turning the paper a sharp, vivid blue [Blue Litmus Paper].
- Acidic and Neutral Behavior: If dipped into a neutral solution (such as pure water) or an acidic substance, the premium leaf remains completely red, signaling that no active base is present [Blue Litmus Paper].
- Alkaline Gas Analysis: Moisten a single leaf with distilled water and hold it near a chemical reaction to quickly confirm the evolution of basic gases like Ammonia (NH₃).
Features
- Genuine Johnson Test Papers (UK): Manufactured in the United Kingdom to the highest international quality control and chemical safety standards.
- High-Capacity 200 Leaves Packet: Packed as a generous book or block containing 200 individual tear-out leaves, providing long-lasting value for large exam classes.
- High-Contrast, Instant Reaction: Yields an unmistakable, bold red-to-blue transition within 1 to 2 seconds of moisture contact [Blue Litmus Paper].
- Resilient Storage Packaging: Shielded in a protective cardboard pocket book that blocks ambient light and dust, preserving testing sensitivity for years.
