Methyl orange solution , 1liter

Product Name: Methyl Orange Solution

Chemical Formula: C₁₄H₁₄N₃NaO₃S (for Methyl Orange)

CAS Number: 547-58-0

Description:

Methyl Orange Solution is a ready-to-use pH indicator solution commonly used in titrations and various laboratory applications. It is a synthetic azo dye that transitions from red at a pH of 3.1 to yellow at a pH of 4.4, making it ideal for determining the endpoint of strong acid-weak base titrations. The solution is prepared to a standard concentration for consistent and reliable results.

Applications:

1. Analytical Chemistry:
   • pH Indicator: Utilized in titrations to determine the acidity or alkalinity of a solution, providing a clear and distinct color change at the endpoint.
   • Strong Acid-Weak Base Titrations: Specifically suitable for titrations involving strong acids and weak bases due to its precise transition range.
2. Educational Use:
   • Teaching Tool: Employed in educational laboratories for teaching acid-base titration techniques and pH determination.
3. General Laboratory Use:
   • pH Testing: Used for general pH testing in various laboratory settings, including research, quality control, and industrial applications.

Specifications:

• Appearance: Clear, orange solution
• Concentration: Typically 0.1% (w/v) Methyl Orange in water
• pH Range: Transitions from red at pH 3.1 to yellow at pH 4.4
• Solubility: Soluble in water

Advantages:

• Ready-to-Use: Pre-prepared solution eliminates the need for weighing and dissolving the indicator, saving time and ensuring accuracy.
• Consistent Quality: Standard concentration ensures reliable and reproducible results in titrations and pH measurements.
• Clear Transition: Provides a distinct color change, making it easy to determine the endpoint of titrations.
