A common technique is the use of indicator dyes to indicate the end point which lies close to the stoichiometric equivalence point, but there are times when we overshoot the end point but may not have sufficient
Explain why it is quantitatively not acceptable to titrate each of the vinegar samples with the NaOH titrant to the same dark pink endpoint? Explain why NaOH is not the best test reagent for detecting Pb2+. Why did the solution turn to pink at the end of the titr...
The bound copper and iron shouldn't give the same peaks as the free material, so you should be able to determine concentration of material in solution. The zinc I'd titrate. Logged woelen Chemist Full Member Posts: 277 Mole Snacks: +40/-2 Gender: The art of wondering makes life wor...

20.Pour 75 mL of this solution into a second 250 mL Erlenmeyer flask (flask 2), add 2 drops of phenolphthalein solution, and titrate to the phenolphthalein color change with 0.20 M NaOH. Record the volume of titrant. You now have a solution of a weak acid in flask 1, and a solution...
to make a cleaning product out of bicarb and vinegar; they probably won'ttitratethe mixture, and so will have a surplus of one substance or the other. Surplus bicarb, as a base, will clean greasy things by, essentially, turning the grease into soap. Surplus vinegar, as an acid, will...
How many mL of 0.343 M HI are needed to titrate 58.4 mL of 0.652 M NaOH to the equivalence point? How many milliliters of 0.0850 m NaOH are required to titrate 50.0 mL of a solution that contains 1.85 g of HCl per liter to the equivalence poin...
to the tips of my toes. In the third week of this earth based purgatory, I sought out a pain clinic to seek out a possible solution to my hellish condition. After all of the agony that I had invested in a cold turkey withdrawal I wasn't about to loose that investment of pain that...
