Do you know any website where I can find chemical and physical properties of common substance (heat capacity, enthalpy of formation, boiling point ecc...)?
Thanks
Ric

In summary, the website RicI mentioned is Pubchem, and it has a lot of information on chemical and physical properties of common substances, but KHCO3 is not that common.

I use and love Pubchem which branches off NCBI if I remember correctly.

Mhm I found it earlier, but no. It lacks lot of information like enthalpy of formation and heat capacity.
I used to know an amazing website, but I can't remember its name

In general best databases are behind a paywall.

Of course, but I though properties of common substances (i.e. CO2, K2CO3, H2S, HCL, stuff like that) would be easy to find. Wikipedia has a some nice stuff, but I am looking for a little bit more informations.

That's the website I used to use, thanks!
But I think KHCO3 is not that common after all
guess I'll have to go to the library...- #10

That site has a lot of information, just not what you are looking for.
Melting Point: Decomposes before melting
http://www.sciencelab.com/msds.php?msdsId=9927398
All it says is "irritant", "avoid contact", "wear respiratory equipment", and CAS# 298-14-6
http://www.chemicalbook.com/CASEN_298-14-6.htm
Plenty of background info. Melting Point 292C
https://www.scbt.com/scbt/product/potassium-bicarbonate-298-14-6
Their MSDS shows:
Melting: 100C
Boiling: 333.6C
Flash Point: 169.8C
Pay attention to MSDS section 11. TOXICOLOGICAL INFORMATION
Many more if you search on the CAS 298-14-6, just not the info you are looking for.
Good Luck!

exactly. Well, I can't do much about it...
1. What is a database for chemical and physical properties?
A database for chemical and physical properties is a collection of data and information related to the chemical and physical characteristics of substances, such as elements, compounds, and mixtures. It includes data such as melting and boiling points, density, solubility, and other properties that are important for understanding and using these substances in various applications.
2. How is data collected for a database for chemical and physical properties?
Data for a database for chemical and physical properties is collected through experiments and measurements conducted by scientists. This can include techniques such as spectroscopy, chromatography, and other analytical methods. Data can also be obtained from published research articles and other reliable sources.
3. What is the importance of a database for chemical and physical properties?
A database for chemical and physical properties is important because it provides a centralized and easily accessible source of accurate and reliable data for scientists, researchers, and other professionals working in fields related to chemistry and materials science. This data is crucial for understanding the behavior and properties of substances, as well as for developing new materials and products.
4. How is a database for chemical and physical properties organized?
A database for chemical and physical properties is typically organized in a systematic and structured manner, with data arranged according to the type of substance, its chemical formula or structure, and its properties. Some databases also include search and filtering features to help users find specific data or substances.
5. How can a database for chemical and physical properties be used?
A database for chemical and physical properties can be used for a variety of purposes, such as predicting the behavior of substances under different conditions, comparing properties of different substances, and identifying potential applications for new materials. It can also be used to support research and development in industries such as pharmaceuticals, materials science, and environmental science.
