What Are Serial Dilutions

We have already seen what dilutions are, and how to calculate them using the simple M1V1 = M2V2 equation. We are now going to look at serial dilutions. These are just multiple dilutions, and we can still use our same equation. Serial dilutions are really useful in chemistry, microbiology, medicine amongst other things. We will run through an example where multiple dilutions are needed and we need to calculate the final concentration. We will also look at a bacteria example, using ratios.
