Product Description
When precision matters in your lab work, EDTA Ca-disodium dihydrate is the go-to chelating agent for accurate complexometric titrations. This analytical-grade chemical from Merck ensures reliable results in water hardness testing, metal ion analysis, and various research applications. Whether you’re a student, researcher, or educator, this high-purity EDTA salt helps eliminate guesswork in your experiments.
EDTA, or ethylenediaminetetraacetic acid, forms stable complexes with metal ions, making it indispensable in analytical chemistry. The calcium disodium salt form is particularly useful because it dissolves easily in water and maintains stability across a wide pH range. This makes it perfect for standardizing solutions and determining metal concentrations with confidence.
At eqipped, we understand the importance of consistent quality in lab supplies. That’s why we source this EDTA dihydrate directly from Merck, a trusted name in chemical manufacturing. The 5 kg pack size is ideal for labs with frequent usage, ensuring you always have enough on hand without constant reordering.

This product is widely used in educational institutions, research labs, and quality control departments. Its versatility extends to environmental testing, pharmaceutical analysis, and even food industry applications where metal ion interference needs to be controlled. The analytical grade certification guarantees minimal impurities, so your results remain unaffected by contaminants.
For those working in academic settings, this EDTA salt is excellent for teaching complexometric principles. Students can clearly observe the color changes during titrations, reinforcing their understanding of coordination chemistry. Researchers appreciate its reliability in quantitative analysis, where even minor variations can impact findings.
How to Use EDTA Ca-Disodium Dihydrate
Preparing a standard EDTA solution is straightforward. Dissolve the required amount in distilled water, then standardize it against a calcium carbonate solution using an appropriate indicator like Eriochrome Black T. The sharp endpoint makes it easy to achieve precise measurements, even for beginners.
For water hardness testing, simply add the EDTA solution to your sample until the color shifts from wine-red to blue. This method is so reliable that it’s used in municipal water treatment facilities and industrial quality control labs worldwide.
Safety and Storage
While EDTA is generally safe when handled properly, it’s always good practice to wear gloves and safety goggles when working with chemical powders. Store the container in a cool, dry place away from direct sunlight. Keep the lid tightly sealed to prevent moisture absorption, which could affect the product’s efficacy.
