wote TITRATION OF AN ACID WITH A BASE 2020 Pre-lab assignment ame In part A of the procedure, you will make a 0.2 M NaOH solution by diluting 6 M NaOH. How many milliliters of 6 M NaOH are required to make 500.0 mL of 0.2 M NaOH? Even though it will be breaking significant figure rules, give the answer to the nearest tenth. In part B of the procedure you will be dissolving oxalic acid dihydrate in water to...

I don't understand what calculations I would have made to create the buffer solution from Part D of the lab. I understood the procedures I took to create the solution but when the report asks to show the calculations used to prepare the buffer solution I am not sure other than mixing the volumes indicated in the procedures section. Thank you pH of Butter Assigned by Instructor 5.12. Measured pH of Assigned B r .9 (Read the procedural Show the...

Need help calculating molatity if the solution in the lab listed below. 4. Place a weigh boat on the scale. Tare the scale and then weigh out approximately 4.1 g of sodium acetate. 5. Record the exact mass (if you were slightly off from 4.1, that’s fine…just write down the actual value so the math is not incorrect later) of the sodium acetate in your lab notes. 6. Transfer the sodium acetate into a 100 mL beaker. 7. Use a...
based on data please help fill out chart and questions 1,2,3 Part II: Neutralization of the Tablet 1. Obtain one of the commercial antacid tablets that your Lab Instructor has assigned you. 2. Weigh and record the weight of the tablet. 3. Crush the tablet using mortar and pestle. 4. Transfer as much of the crushed tablet as you can onto a weigh boat. 5. Weigh the tablet and weigh boat, and record this value. 6. Pour the entire contents...
