Scenario 3: In small amounts (-1 ppm = 1 mg/L) copper (II) ions are used as an algaecide in swimming pools. Blue Water Pool Treatments (BWPT), a producer of algaecide and other pool chemicals, recently had an incident at one of their manufacturing plants; someone added too much copper sulphate to the product mixture, resulting in an algaecide that is more concentrated than the...

I'm not sure about how I'm supposed to find NaOH
concentration from a strong acid and strong base titration. I'm
thinking that 2.5×10^-8 mol per L that I calculated would make the
moles of NaOH 2.5x10^-8 mol since it's a one to one
ratio.

1. A student carries out a back titration to determine the concentration of ammonium chloride in a solution. The student collects 10.80 mL of the original NH4Cl solution and dilutes it to 250.0 mL (we will refer to this as the dilute NH4Cl solution). Then 25.00 mL of the dilute NH4Cl solution are transferred to an Erlenmeyer flask and 25.00 mL of 0.1963 M NaOH are added. Calculate the moles of NaOH added to this Erlenmeyer flask. 2. In the...

The concentration of each solution will be given in molarity (M). Molarity is a quantity that expresses the moles of solute present per liter of solution. A sodium hydroxide solution is labeled as 0.1020 M. i. Write that as a ratio of moles and liters. ii. If 11.25 mL of the 0.1020 M NaOH solution is used to titrate a solution, then how many moles of NaOH does that represent? iii. If the number of moles of unknown acid neutralized are determined to...
