About Universal Indicator PH 4-11 100ml
Universal Indicator Solution pH 411 is a laboratory pH indicator solution used for visual determination of acidity and alkalinity across the pH range 411. Qualigens product code Q38123, 100 mL pack.
Reliable pH Range CoverageThis universal indicator provides accurate pH assessment between 4 and 11, making it suitable for most common acid-base testing in laboratories. The clear color transitions enable easy distinction of pH changes during chemical analysis, promoting efficiency and confidence in results.
Convenient and Safe PackagingSealed in a durable plastic bottle, the 100 ml volume is ideal for routine lab use and minimizes the risk of spills. Proper storage instructions and long shelf life (5 years) ensure the indicator remains effective and safe to handle when kept in a cool, dry environment with the cap tightly closed.
Simple Visual DetectionThe green-coloured liquid changes shades according to the acidity or alkalinity of the tested solution, letting users immediately interpret pH levels without the need for specialized instruments. This process is straightforward and highly effective for rapid, on-the-spot analysis in laboratory settings.
FAQ's of Universal Indicator PH 4-11 100ml:
Q: How is Universal Indicator pH 4-11 used in laboratories?
A: Universal Indicator pH 4-11 is added directly to a laboratory solution. The color change observed indicates the solution's pH level, allowing for quick visual determination within the pH 4-11 range. This method simplifies acid-base analysis without requiring electronic pH meters.
Q: What are the storage requirements for this indicator?
A: Store the universal indicator in a cool, dry place with the container tightly closed. Proper storage ensures the product's stability and maintains its effectiveness throughout its 5-year shelf life.
Q: When should this indicator be selected over other pH indicators?
A: This universal indicator is ideal when a wide pH range (4-11) screening is needed and rapid, qualitative results are sufficient. It is especially useful in educational, research, and quality control laboratories requiring a simple acid-base analysis tool.
Q: Where is Universal Indicator pH 4-11 commonly applied?
A: It is widely used in schools, colleges, research laboratories, and industrial labs for chemical analysis, teaching acid-base concepts, and monitoring pH in experimental procedures.
Q: What is the benefit of using this universal indicator mixture?
A: The key benefit is immediate, visual feedback on the pH of solutions, which enhances workflow efficiency and enables quick decision-making in various laboratory analyses.
Q: How should this product be handled for maximum safety?
A: Handle the universal indicator with care, keeping it away from heat sources due to its low flash point (12C). Always close the bottle securely after use to prevent evaporation or contamination.
Q: What is the typical appearance and physical state of this universal indicator?
A: It appears as a green-coloured, clear liquid with a density of 0.85-0.90 g/mL and is supplied in liquid form in plastic bottles for easy handling.
