Question 9 of 21 > O Macmillan Learning You decide it is time to clean your pool since summer is quickly approaching. Your pool maintenance guide specifies that the chlorine, Cl₂, concentration of the pool should be between 1 and 3 ppm. In order to determine if your pool is safe to swim in, you send a sample of pool water to a chemist for analysis of the Cl₂ content. The chemist reports a chlorine concentration of 3.92 × 10-5 M. Convert the concentration of Cl₂ to parts per million (ppm). concentration: 2.71 Incorrect Attempt 3 ppm

5:15 1 ull 4G Discussion Assignment #6 O o o INFO DISCUSSION Discussion Assignment #6 Due:Wednesday, 14 Oct 2020, 3:00 PM In titration, one solution is added to another solution until a chemical reaction between the components in the solutions has run to completion. The solution being added is called the titrant, and we say that it solution. The completion of the reaction is usually shown by a change of color caused by a substance called an indicator. used titrate the other A typical titration proceeds in the following way. A specific volume of the solution to be titrated is poured into an Erlenmeyer flask. For example, 15.0 mL of a sulfuric acid solution of unknown concentration is added to a 250 mL Erlenmeyer flask. An indicator is then added to the flask, which changes color when the reaction is complete. The titrant in this example is potassium hydroxide, having a concentration of 0.121 M. The titrant is added to a buret. After slowly adding the titrant to the flask, the reaction…
