For laboratories and research institutions, the reliability and precision of chemical reagents are non-negotiable. Barium Chloride Dihydrate (CAS 10326-27-9) is a fundamental compound in analytical chemistry, widely recognized for its utility in specific quantitative analyses. Understanding its properties and knowing how to source it effectively from a trusted Barium Chloride Dihydrate supplier ensures laboratory accuracy.

The Analytical Significance of Barium Chloride Dihydrate

One of the most prominent uses of Barium Chloride Dihydrate in analytical chemistry is its role as a reagent for the gravimetric determination of sulfate ions (SO₄²⁻). This method is a classic technique used to accurately quantify the amount of sulfate present in a sample. The process typically involves dissolving the sample and then adding a solution of Barium Chloride Dihydrate. The barium ions react with sulfate ions to form an insoluble precipitate, barium sulfate (BaSO₄). This precipitate is then filtered, dried, and weighed. The mass of the barium sulfate precipitate is directly proportional to the amount of sulfate originally present in the sample.

The reaction is represented as:

BaCl₂(aq) + SO₄²⁻(aq) → BaSO₄(s) + 2 Cl⁻(aq)

The high purity and water solubility of Barium Chloride Dihydrate are critical for the success of this analytical method. Impurities in the reagent could lead to inaccurate weight measurements or side reactions, compromising the integrity of the analysis. Therefore, laboratories often search for 'barium chloride dihydrate supplier China' to find manufacturers that offer high-grade reagents with verified purity, typically exceeding 99%.

Procuring Analytical Grade Reagents

When looking to buy Barium Chloride Dihydrate for laboratory use, it is essential to specify the required grade. Analytical Reagent (AR) grade or higher is usually preferred for quantitative analysis to ensure minimal interference. Buyers should prioritize suppliers who provide detailed Certificates of Analysis (CoA) for each batch, confirming the absence of interfering ions and confirming the stated assay. Exploring 'barium chloride dihydrate price per kg' from reputable suppliers allows laboratories to budget effectively for their consumables.

For laboratories needing this reagent, finding a reliable Barium Chloride Dihydrate manufacturer is key. Many research and quality control labs seek online sources, frequently using search terms like 'buy Barium Chloride Dihydrate online'. Ensuring the supplier offers convenient ordering, secure packaging, and prompt delivery is also important for uninterrupted laboratory operations.

Safety and Handling in the Lab

As with all chemical reagents, proper safety protocols must be followed when handling Barium Chloride Dihydrate. It is a toxic substance, and laboratory personnel should be thoroughly familiar with its Safety Data Sheet (SDS). Appropriate personal protective equipment (PPE), such as gloves, safety glasses, and lab coats, must be worn. Laboratories should have adequate ventilation and emergency equipment, including spill kits and eye wash stations, readily available.

In conclusion, Barium Chloride Dihydrate is an indispensable tool in the analytical chemistry laboratory, particularly for sulfate determination. By prioritizing high-purity grades, verifying supplier credentials, and adhering to strict safety practices, laboratories can confidently utilize this compound to achieve precise and reliable analytical results.
