Question- A 20.00-mL NaBr solution is treated with 40.00mL of 0.278 M AgNO3. The precipitate is filtered, washed and the filtrate containing a few drops of Fe3+ is titrated by a 0.230 M KSCN solution. The solution becomes red after 28.67mL of titrant.
1) What is the molar concentration of the NaBr solution?
2) What is causing the red color in solution?
Any assistance is greatly appreciated
