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 Cl, content. The chemist reports a chlorine concentration of 3.53 x 10-5 M. Convert the concentration of Cl, to parts per million (ppm). ppm

) A stock solution of nitric acid is found in the back of the chem stock room, but the concentration on the label is illegible. Andy decides to determine its concentration with a titration, so it can be relabeled. She prepares a stock solution of NaOH by adding 150.g to 2.50 L of water. What is the concentration of the NaOH stock solution? She adds an indicator to a 200. mL sample of the nitric acid solution and find that it takes 670. mL of the NaOH solution to reach the equivalence point. How many moles of NaOH were added? What is the concentration of the stock solution of nitric acid?

4) Environmental chemists mostly define solutions in molar units. Environmental engineers typically use mass units like mg/L. Convert the following concentrations: Solute mg/L Nacl 0.01 Na2CO3 10.0 NH3 1.0 x 106 Since the conversions are a function of molar mass, a spreadsheet makes quick work of these calculations if molar mass is entered as a known.

5. Calculate the concentration of the hydrochloric acid if a 20.00 mL sample is titrated with standard sodium carbonate solution. 2 HCI (aq) + Na₂CO3(aq) → H₂O (1) + CO₂(g) + 2 NaCl (aq) The titration required 10.00 mL of 0.250 mol/L sodium carbonate to neutralize the acid. rn Lakes College
For their first trial, a student pipettes 5.00 mL of a vinegar solution into an Erlenmeyer flask. The student titrates the vinegar with standardized NaOH with a molarity of 0.437 M. The volume of titrant used was recorded in the table above. Calculate the molarity of the vinegar solution for this trial. Enter a number without units.
In analytical chemistry, one of the key steps in quantitative analysis is the determination of the concentration of an analyte in a sample. Consider a scenario where you need to determine the concentration of a particular metal ion in a water sample. Design an analytical procedure and discuss the key steps involved in obtaining an accurate and precise concentration measurement.
A chemist samples a river's water to measure the amount of fertilizer runoff from the area farms. In a 0.0740 L sample, the chemist measures 562 µg of nitrate. Express the concentration of nitrate in parts per million (ppm) and parts per billion (ppb). Assume the density of the river water sample is 1.00 g/mL. concentration: concentration: ppm ppb
