Solve the following with chemsitry knowledge. QUESTIONS 1. What is the molarity of each of the following solutions? You pipet 25.00 mL of 0.355 M KCI into a 100.00 mL volumetric flask and fill to the mark a. tRTO CONSTANTE b. You pipet ten milliliters of the solution from part (a) into a fifty millaliter volumetric flask and dilute to the mark. You pipet five milliliters ofthesolution from part (b) into a beaker and then pipet twenty milliliters of DI...
I need it right now, please help me?? PROCEDURE PART I: DILUTING THE VINEGAR SOLUTION The vinegar solution must be diluted by a factor of 5 to be suitable for titration. 1. Obtain - 20 ml of the stock vinegar solution from the fume hood. 2. Using the 10-ml. pipet, pipet" 10 mL of the stock solution to a 50-ml volumetric flask. 3. Fill the volumetric flask to the calibration line with distilled water. Be sure not to go over...

lab report titration help please! additional images on lab report 3. Federal standards require that any commercial material called "vinegar" must contain as cast acetic acid. According to your results in question 4, does the vinegar sample you titrated meet the Federal standards? Explain why or why not.

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
