For example, mixing Web• Both the concentrated bleach and hydrochloric acid are damaging to skins, eyes and clothing. • Avoid breathing the vapors from the bleach and acid as they are irritants to the respiratory system. • The addition of hydrochloric acid to bleach may produce chlorine gas in Part B, Step 5, so this step should be completed in a fume hood.
Web3 PROCEDURE Each pair of students will titrate one brand of commercial liquid bleach to find the amount of “available chlorine” and the percent, by mass, of sodium hypochlorite in a commercial liquid bleach. Part A: Standardization of Na2S2O3 1. Fill a buret with the provided Na2S2O3 solution. 2. WebConcentration of hypochlorite in diluted bleach solution = 0.0578 M Therefore, concentration of hypochlorite in undiluted bleach solution = 0.0578 x 10 M = 0.578 M Percentage (w/v) of hypochlorite (NaOCl) in bleach = 74.5 x 0.578 / 10 = 4.31% student questions Give one reason why, in making up the solution of diluted bleach, a
