What is a major source of ions in wastewater?

Homework Answers

Answer #1

Solution :

  • The major ions present are ,

Cations - calcium Ca2+, magnesium Mg2+, Sodium Na+ , Potassium K+

Anions - Bicarbonate HCO3− , Carbonate CO3−, sulfates SO4− , chlorides Cl−

  • The concentrations of four major cations, Ca++, Mg++, Na+, and K+, and four major anions, HCO3−, CO3−, SO4−, and Cl−, usually constitute the total ionic salinity of the water for all practical purposes.
  • Concentrations of ionized components of other elements such as nitrogen (N), phosphorus (P), and iron (Fe) and numerous minor elements are of immense biological importance but are usually minor contributors to total salinity.

Wastewater resulting from metal processing is polluted with cadmium ions, Cd2+, which must be removed from the water. In one method, the water is treated with a solution of concentrated sodium hydroxide. Suppose 1.00 x 102 L of wastewater containing 1.2 x 10–5 M Cd2+ is treated with 1.0 L of 6.0 M NaOH solution.   The Ksp of Cd(OH)2 is 7.2 x 10-15 What is the residual concentration of aqueous cadmium ion after treatment?

Heavy metal ions like lead(II) can be precipitated from laboratory wastewater by adding sodium sulfide, Na2S. Will all the lead be removed from 13.6 mL of 7.00×10-3 M Pb(NO3)2 upon addition of 13.3 mL of 0.0123 M Na2S? If all the lead is removed, how many moles of lead is this? If not, how many moles of Pb remain?
