Humidity Indicator: As a key raw material for color-changing silica gel, its color changes with ambient humidity, providing a direct indicator of humidity.
Catalysts and Chemical Intermediates: Used as a catalyst in organic synthesis and other fields, or as a basic raw material for preparing other cobalt compounds.
Feed Micronutrient Additive: Supplements ruminants with essential cobalt, preventing malnutrition caused by cobalt deficiency.
Chemical Education and Experiment Reagents: Used for classroom demonstrations and chemical experiments to illustrate principles such as ionic color and hydration.
Q1: Why does its color change with humidity?
A1: The color change originates from changes in the hydration number of the crystals. The structure of the complex changes when it absorbs or loses water, causing differences in visible light absorption.
Q2: How to store it correctly to prevent deterioration?
A2: It should be stored in a sealed container in a cool, dry, and well-ventilated place, avoiding prolonged contact with air to prevent moisture absorption and deliquescence.
Q3: Can it come into direct contact with skin?
A3: No. Protective measures should be taken during handling to avoid inhaling dust or direct contact. Thorough cleaning is required after use.
