CH 111 - Exp 6 Titration of Fruit Juice(2) (2) (Protected View) - Word (Unlicensed Product) Help Tell me what you want to do This experiment is highly similar to the titration of HCI with NaOH so there is no video accompanying this lab. In this titration orange juice is used as the acid in place of HCI. That is because most fruit juices are acidic, with citric acid (H3C6H5O7) being one of the more common acids, especially and not...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
