This could be a nice place to start posting chemistry/biology questions. And if you want an entire topic to be covered, this is the place to suggest it.
I second a buffering solution post! How they work, when you would use them, etc…
I asked some questions on the last post but you can post the answers in a separate post re: buffering solutions. I read them all! Thanks for sharing your knowledge!!
You'll need to upload them to a free image hosting service first—Imgur (http://imgur.com/) is great and doesn't require you to sign up for an account. Simply click " New Post" at the top of the page, drag your images into the window that pops up, and the images will automatically upload. From there you can hover the images and copy the URL that appears; simply paste that URL into your post on a new line and the image will appear automatically when you post!
