1. Basic Information and Parameters

Sodium bromate, with the chemical formula NaBrO₃, has a CAS number of 7789 - 38 - 0. It is an odorless, white crystalline powder. The molar mass of sodium bromate is approximately 150.89 g/mol. It has a density of about 3.339 g/cm³ at 25 °C. Sodium bromate is soluble in water, and the solubility in water increases with temperature. For example, at 0 °C, the solubility is about 27.5 g/100 mL of water, while at 100 °C, it can reach about 90.8 g/100 mL of water. It is a strong oxidizing agent, which means it can react vigorously with reducing agents and combustible materials.

2. Product Uses

In the chemical industry, sodium bromate is widely used as an oxidizing agent in various chemical reactions. It can be used in the synthesis of organic compounds, such as in the oxidation of certain alcohols to aldehydes or ketones. In the food industry, it was previously used as a flour - treating agent. It can improve the strength and elasticity of the dough, resulting in better - quality bread and other baked goods. However, due to potential health risks, its use in food has been restricted in many countries. In the laboratory, it is often used in analytical chemistry as a standard oxidizing agent for titration experiments to determine the concentration of reducing substances.

3. Product Usage

When using sodium bromate, strict safety protocols should be followed. Wear appropriate personal protective equipment, including safety goggles, gloves, and a lab coat. In a laboratory setting, for titration experiments, first, prepare a standard solution of sodium bromate with a known concentration. Dissolve an appropriate amount of sodium bromate in distilled water and make up to a specific volume in a volumetric flask. Then, use a burette to add the sodium bromate solution to the sample containing the reducing agent until the end - point of the reaction is reached, which is usually indicated by a color change. In industrial applications, such as in the synthesis of organic compounds, the reaction conditions, including temperature, pressure, and reaction time, need to be carefully controlled. Sodium bromate should be added slowly to the reaction mixture to avoid violent reactions.

4. Product Use Case Studies

Case 1: Organic Synthesis in a Chemical Factory
A chemical factory was synthesizing a specific aldehyde from an alcohol. They used sodium bromate as the oxidizing agent. First, they dissolved the alcohol in a suitable organic solvent in a reaction vessel. Then, they added a catalytic amount of a transition - metal catalyst to enhance the reaction rate. After that, they slowly added a solution of sodium bromate drop - by - drop while maintaining the reaction temperature at around 60 °C. The reaction was monitored by thin - layer chromatography. After about 3 hours, the reaction was complete, and they were able to obtain the desired aldehyde with a high yield of about 85%.
Case 2: Analytical Chemistry in a Research Laboratory
In a research laboratory, scientists were analyzing the content of a reducing sugar in a food sample. They prepared a sodium bromate standard solution with a concentration of 0.1 mol/L. They took a known mass of the food sample and dissolved it in water. Then, they titrated the sample solution with the sodium bromate solution using a suitable indicator. The end - point of the titration was clearly observed by the color change of the indicator. From the volume of sodium bromate solution used in the titration, they were able to accurately calculate the content of the reducing sugar in the food sample.
