Reaction of alpha olefin sulfonate (AoS)

In summary, the chemical reaction between AOS and calcium carbonate results in a precipitate. AOS also reacts with ferrous sulphide to produce ferrous sulfonate and sodium sulfide. However, no reaction will occur between AOS and anhydrite, barium sulphate, ferrous carbonate, or strontium sulphate as they are either soluble or insoluble in water.

Homework Statement


Chemical reaction between alpha olefin sulfonate (AOS) and calcuim carbonate?
I want to know the chemical reaction between alpha olefin sulfonate (AOS, RCH=CH(CH2)nSO3Na) and calcuim carbonate and also AOS with the following materials.
1.Anhydrite (CaSo4)
2.Barium Sulphate (BaSo4)
3.Ferrous Sulphide (FeS)
4.Ferrous Carbonate (FeCO3)
5.Strontium Sulphate (SrSO4)


Homework Equations



can i know the mechanism and the product between AoS and the six compounds below..


The Attempt at a Solution



what i know,olefin sulfonate is a salt, a salt is rarely react with insoluble salt.

The product of reaction between a salt and insoluble salt is a precipitate. So, the products between AOS and calcium carbonate is a precipitate. 1.Anhydrite (CaSo4) : The reaction between AOS and anhydrite will not happen because both are soluble in water.2.Barium Sulphate (BaSo4) : The reaction between AOS and barium sulphate will not happen because both are soluble in water.3.Ferrous Sulphide (FeS) : Ferrous Sulphide reacts with AOS to produce ferrous sulfonate and sodium sulfide.4.Ferrous Carbonate (FeCO3) : The reaction between AOS and ferrous carbonate will not happen because both are insoluble.5.Strontium Sulphate (SrSO4) : The reaction between AOS and strontium sulphate will not happen because both are soluble in water.
 

FAQ: Reaction of alpha olefin sulfonate (AoS)

1. What is alpha olefin sulfonate (AoS)?

Alpha olefin sulfonate is a surfactant and anionic detergent commonly used in cleaning and personal care products. It is derived from alpha olefins, which are long-chain hydrocarbons, and is often found in the form of a white powder or liquid.

2. How does AoS work as a cleaning agent?

AoS molecules have both hydrophobic (water-repelling) and hydrophilic (water-attracting) ends, making them effective at removing dirt and oils from surfaces. The hydrophobic end attaches to the dirt, while the hydrophilic end allows it to be washed away with water.

3. Is AoS safe to use in household products?

When used as directed, AoS is generally considered safe for household use. However, it is important to follow the recommended concentrations and precautions provided by the manufacturer to avoid any potential hazards.

4. Can AoS be used in environmentally-friendly products?

Yes, AoS can be used in environmentally-friendly products. It is biodegradable and can be derived from renewable resources, making it a more sustainable option for cleaning and personal care products.

5. Are there any potential risks or side effects of using products containing AoS?

In high concentrations, AoS may cause skin and eye irritation. It is important to follow safety precautions and use proper protective equipment when handling concentrated forms of AoS. Additionally, some individuals may have allergies or sensitivities to AoS, so it is always recommended to read product labels and test on a small area before use.
