Hey guys!, I just want to know what will happen when you heat up lanthanum hydroxide La(OH)3 from 20 degree Celsius to 900 degree Celsius in a furnace with O2 gas. Is the mas of La(OH)3 increases? and why? thanks in advance!
No. It dehydrates.ralden said:mas of La(OH)3 increases?
Lanthanum hydroxide is a chemical compound composed of lanthanum and hydroxide ions. It is important because it has various industrial and scientific applications, such as in catalysis, glass production, and fuel cells.
The melting point of lanthanum hydroxide is approximately 920°C (1,688°F).
Lanthanum hydroxide can be heated using various methods, including flame heating, electric heating, and microwave heating. The most common method is flame heating using a Bunsen burner or a furnace.
When lanthanum hydroxide is heated, it undergoes a series of chemical reactions. First, it decomposes into lanthanum oxide (La2O3) and water vapor (H2O). The lanthanum oxide then reacts with the water vapor to form lanthanum hydroxide again, creating a cycle of decomposition and reformation.
Yes, it is important to handle lanthanum hydroxide with caution as it can cause irritation to the skin, eyes, and respiratory system. It is also flammable and should be heated in a well-ventilated area. Additionally, proper protective gear should be worn when handling and heating this compound.
