A common way of removing Cr3+ from solution is precipitation of Cr(OH)3(s). An environmental engineer tells you that adjusting the pH to 8.5 will decrease the total soluble Cr(III) to below 1 mg/L. Is this true? In other words, is the solubility of Cr(III) in the presence of Cr(OH)3(s) at a pH of 8.5 less than 1 mg/L? the pKspof Cr(OH)3(s) is 30.22. Note: This question is in 5th edition of Chemistry for Environmental Engineering and Science. Chapter 4, Question...

Let us assume that Cr(OH)3(s) is completely insoluble, which signifies that the precipitation reaction with NaOH(aq) (presented in the transition) would go to completion. Cr3+(aq)+3NaOH(aq) → Cr(OH)3(s)+3Na+(aq) If you had a 0.600 L solution containing 0.0130 M of Cr3+(aq), and you wished to add enough 1.26 M  NaOH(aq) to precipitate all of the metal, what is the minimum amount of the NaOH(aq) solution you would need to add? Assume that the NaOH(aq) solution is the only source of OH−(aq) for the...
