Catalyst: Catalysts are chemicals that modify the rate of a reaction by changing the course of the reaction. Catalysts can increase or decrease the rate of the reaction without being consumed in the reaction.
- Most of the time, catalysts are used to accelerate or increase the rate of a reaction.
- Chemical bonds between atoms present in molecules of different elements or compounds are broken or recreated using catalysts, however, if we look at things more closely.
- In short, catalysts promote the molecular reaction and facilitate and accelerate the entire reaction process.
- Catalysts come in three different forms: solid, liquid, and gaseous.
- Metals or their oxides, such as sulfides and halides, are among the solid catalysts.
- As catalysts, semi-metallic substances including silicon, aluminum, and boron are also employed.
- The same is true for the employment of pure liquid and gaseous elements as catalysts.
- These substances are sometimes combined with suitable solvents or carriers.
- It is a substance that can be used to decrease or increase the rate of reaction.
- While salt can be viewed as a catalyst in the reaction, it serves a different purpose from that of other catalysts.
- Due to the relatively thin tarnish coating on aluminum, copper II sulfate and aluminum react very slowly (aluminum oxide).
- The process can accelerate if the aluminum oxide layer is damaged or removed.
Hence, salt is a catalyst.
