WebTo vary the concentration of the acid you need to dilute it by measuring portions of acid in a measuring cylinder and then portions of distilled water in another measuring cylinder and adding them to the conical flask. Choose a suitable volume of acid to match the size of the flask, e.g. 40 cm 3. You don't want to use acid that is stronger than ...
