Here you can ask for free questions on chemistry and related areas. I will try to answer these questions as quickly as possible. Inappropriate questions/comments will be erased by me without justification and feedback.
In the past this free service has been frquently used, therefore, please understand that answers might take a few days. Please do not ask multiple questions to different topics at once, but use a separate question form for each topic.
From October 2001 to October 2006
2296 questions were answered.
To ask a question, please use the form provided (click the green arrow below). You can ask an open question (question and answer is visible to all in the archive, a code will be sent to you to easily find the answer to your question) or a private question (question and answer is only visible to you, a code will be sent to you to access in combination with your e-mail address the answer). In any case, you have to provide an e-mail address so that you can be notified when your question is answered. Your e-mail address will never be visible to anyone (regardless if your question is open or private).
You can find answered questions in the archive. You will have to give the code provided to you by e-mail to easily find the answer to your question and - if the question is private - use the code and your e-mail address for authentification to access the answer.
