Silica gel blue self indicating 25kg
Silica gel blue self-indicating is a type of desiccant made from a form of silicon dioxide that appears blue when it is dry and changes color to pink when it becomes saturated with moisture. The self-indicating feature allows the user to easily identify when the silica gel needs to be replaced or recharged. It is commonly used in packaging, electronics, and other industries to prevent moisture damage to products during storage and transportation.
Sodalime with indicator 500gm
Sodalime with an indicator is a substance often used in medical and laboratory settings, primarily for the absorption of carbon dioxide (COā) and certain other acidic gases. The indicator in sodalime serves a crucial function by visually signaling when the sodalime has been exhausted and can no longer effectively absorb COā. Hereās a detailed look at its components, functionality, and use:
Components of Sodalime
- Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH): These strong bases are the active components that react with COā to form carbonates and water.
- Calcium Hydroxide (Ca(OH)ā): This provides a medium in which the reaction takes place and also participates in the COā absorption process.
- Water (HāO): Necessary for the chemical reaction.
- Indicator Dye: Changes color based on the pH level, signaling when the sodalime is no longer effective.
Chemical Reaction
The primary reaction for COā absorption can be summarized as: CO2+H2OāH2CO3text{CO}_2 + text{H}_2text{O} rightarrow text{H}_2text{CO}_3CO2ā+H2OāH2CO3ā H2CO3+2NaOHāNa2CO3+2H2Otext{H}_2text{CO}_3 + 2text{NaOH} rightarrow text{Na}_2text{CO}_3 + 2text{H}_2text{O}H2CO3ā+2NaOHāNa2āCO3ā+2H2āO Secondary reactions may involve calcium hydroxide: Na2CO3+Ca(OH)2ā2NaOH+CaCO3text{Na}_2text{CO}_3 + text{Ca(OH)}_2 rightarrow 2text{NaOH} + text{CaCO}_3Na2āCO3ā+Ca(OH)2āā2NaOH+CaCO3ā
