Fehling Solution 1 and 2

Original price was: $4,500.00.Current price is: $4,000.00.

Fehling’s solution is used in chemistry to detect the presence of reducing sugars. It is composed of two separate solutions that are mixed in equal volumes just before use.

Fehling’s Solution 1

  • Composition: This solution contains copper(II) sulfate (CuSO₄).
  • Appearance: It is a deep blue solution.
  • Preparation: Typically prepared by dissolving copper(II) sulfate in water.

Fehling’s Solution 2

  • Composition: This solution contains a mixture of potassium sodium tartrate (Rochelle salt) and sodium hydroxide (NaOH).
  • Appearance: It is a clear, colorless solution.
  • Preparation: Potassium sodium tartrate and sodium hydroxide are dissolved in water.

Description

Uses of Fehling Solution 1 and 2

Detection of Reducing Sugars

Fehling’s solutions are commonly used to test for the presence of reducing sugars in various samples, such as:

  • Food Products: To identify the presence of sugars like glucose and fructose in foods and beverages.
  • Biological Samples: To detect reducing sugars in blood or urine samples, which can be important for diagnosing conditions like diabetes.
  • Chemical Research: In organic chemistry labs to analyze carbohydrates and other compounds.

Distinguishing Aldehydes from Ketones

Fehling’s solutions are used to differentiate between aldehydes and ketones:

  • Aldehydes: These will react with Fehling’s solution, reducing the copper(II) ions to copper(I) oxide, resulting in a red precipitate.
  • Ketones: These generally do not react with Fehling’s solution, so no color change occurs.

Educational Demonstrations

  • Teaching Tool: Fehling’s solutions are often used in educational settings to demonstrate redox reactions and the properties of reducing sugars.

Quality Control in Manufacturing

  • Food and Beverage Industry: Used to monitor sugar content in products.
  • Pharmaceuticals: To ensure the purity and composition of certain medicinal preparations.

Analytical Chemistry

  • Qualitative Analysis: Used in analytical chemistry for qualitative tests to identify the presence of specific functional groups or compounds.

Aluminum Ammonium Sulphate

Original price was: $650.00.Current price is: $500.00.
Aluminum ammonium sulfate, also known as ammonium alum or just alum, is a chemical compound with the formula (NH4)Al(SO4)2·12H2O. It's a white crystalline solid commonly used in water purification, leather tanning, and as a mordant in dyeing textiles. In water purification, alum acts as a coagulant to remove impurities by causing suspended particles to clump together, making it easier for filtration to remove them. In leather tanning, it helps to stabilize the leather by tightening the collagen fibers. And in dyeing textiles, alum helps the dye adhere to the fabric. However, it's important to note that excessive exposure to aluminum compounds like alum can be harmful, so it's typically used with caution and proper safety measures.

Ammonia Solution 2.5litres

Original price was: $4,500.00.Current price is: $4,000.00.
An ammonia solution is a solution of ammonia (NH3) gas dissolved in water. It is a clear, colorless liquid with a pungent odor and a basic pH. The concentration of ammonia in the solution can vary, and is typically expressed in terms of percent by weight or by volume. Ammonia solutions are commonly used in a variety of applications, including cleaning agents, fertilizers, and as a precursor to other chemicals. They are also used in industrial processes such as refrigeration, gas purification, and water treatment. Ammonia solutions can be dangerous if not handled properly, as they are highly corrosive and can release toxic fumes if mixed with certain chemicals

Anhydrous Aluminum Chloride

Original price was: $1,183.00.Current price is: $950.00.
Anhydrous aluminum chloride, often represented as AlCl3, is a chemical compound composed of aluminum and chlorine. "Anhydrous" means it lacks water molecules in its structure. It's a white or pale yellow solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. This property makes handling it a bit tricky since it can form a solution with water vapor in the air, turning into a fuming liquid.
