NaOH (the titrant) has neutralized all of the Acetic Acid, leaving Acetate while in the beaker. At this time, the moles of NaOH added is such as the moles of acetic acid to begin with from the beaker.Another technique for locating the top level will be to plot the first spinoff from the titration curve, which supplies its slope at Every lev… Read More


The permanganate approach is another prevalent system for measuring COD. It will involve incorporating a recognized surplus of potassium permanganate to your acknowledged volume of sample while in the existence of sulfuric acid.The improve in DO focus over five times represents the "oxygen demand" for respiration from the aerobic biological… Read More
