How Do You Calculate Concentration. Let's assume you are titrating a strong acid (10 ml unknown concentration hcl) with a strong base (1.0 m naoh). It is calculated from a point from the upstream to another point of the downstream which is at the drain.
How do you find the initial concentration if you are only given the from www.homeworklib.com
