Oxalic acid and potassium permanganate react according to the shown net ionic equation.
Titration of a 20.0 mL aqueous solution of oxalic acid required 23.24 mL of 0.09113 M aqueous potassium permanganate. Calculate, to 3 significant figures, the concentration of the oxalic acid solution.
A 58.3 mg sample containing is dissolved in 1.0 M . If 23.6 mL of 0.010 M is required to reach the end point of the titration, what is the mass percent (w/) of tin in the original sample?
A 0.357 g sample contains only lead(II) iodide and sodium iodide in 100 mL of distilled water. Titration to Fajans’s endpoint requires 22.37 mL of 0.050 M silver nitrate. What is the mass percent (w/w) of lead(II) iodide in the sample?
