- A 750. mL sample of 0.13 M K2CO3(aq) is combined with 250. mL of 0.13 M Cu(NO3)2(aq) at a given temperature. At the same temperature: Ksp for CuCO3 = 1.4 × 10–10Ksp for KNO3 = 1.4 × 1010 Which of the following statements is true?arrow_forwardHydrogen peroxide solutions can easily be decomposed by dust, trace amounts of metals or light. It istherefore necessary to periodically determine the purity of the peroxide solutions.This can be done via a redox titration as follows: The density of a particular surgical grade hydrogen peroxide solution is 1.11g.cm-3. Exactly 10 mL of this solution was pipetted and quantitatively transferred, along with a sufficientamount of a dilute sulphuric acid solution, into a 250.00 mL volumetric flask and made up to the mark. A 25.00 mL portion of this diluted solution is pipetted into a conical flask, and titrated with a0.372 M KMnO4 solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns apersistent bright pink due to the presence of excess permanganate ions.
