One thousand pounds of 90 % sulfuric acid by mass is to be fed to a batch reactor. A waste acid stream containing 40 % sulfuric acid by mass is available to a process engineer. Also available to the engineer is unlimited amount of 98 % sulfuric acid by mass. The waste acid is used to dilute the 98 % sulfuric acid by mass to produce the 90 % sulfuric acid by mass. (i) (ii) Draw a flow chart (Block flow diagram) of the mixing process Calculate how much of the 40 % sulfuric acid waste acid and the 98 % sulfuric acid will be required to provide the feed (also referred to as the charge) for the reactor
