2,5 ml volume has taken from an “hypothetic” solution which includes (3+) Sb and (3+) Fe and at the titration with 0.1004 N KMnO4, the wasted amount has found as 16,4 mL. The other 2,5 mL that has taken, has reduced with Zn after that, this 2,5 mL solution has titrates with the same KMnO4 solution solution and the wasted amount is 26,5mL. With these datas find the %concentrations of the ions at the solution.

A buffer was made by mixing 0.1886 moles of CH3CH2CO2H with 0.1517 moles of KCH3CH2CO2 and diluting to exactly 1 liter. What will be the pH after addition of 10.00 mL of 0.2441 M HBr to 50.00 mL of the buffer? Ka(CH3CH2CO2H) = 1.300e-5. Note: only a portion of the original buffer is used in the second part of the problem. Key Concept: Buffers resist pH change and are prepared by mixing the conjugate acid and base together. Addition of either a strong acid or a strong base will cause a small shift in pH to a lower or higher pH, respectively.Strategy: Determine the moles of HA and A− the buffer prior to addition of either a strong acid or base by multiplying by the molarity and volume (50 mL) → determine mole of strong acidadded to the buffer. Adjust the moles to account for loss of conjugate base and formation of conjugate acid with addition of a strong acid or loss of conjugate acid and formation of conjugate base with addition of a strong base → use Henderson-Hasselbach equation to…
