What is a Stock solution? What is a working solution? - Dr K

In this video, we are going to answer the following questions: What is a stock solution? What is a working solution? Why do we need a stock solution? How to prepare a stock solution? Having stock solutions and working solutions is very common in a laboratory. We are going to start by describing what is a stock solution. Then, we will look at what is a working solution. Once we have an idea of what stock solutions and working solutions are, we will look into the reason why we need stock solution and lastly how to prepare a stock solution.
