BUFFER CAPACITY EXPERIMENT Part 1: Preparation and pH Meter Calibration Prepare 50 mL of 0.5 M acetic acid from a concentrated stock. Prepare 50 mL of 0.5 M sodium hydroxide from a solid. Part 2: Buffer Capacity Transfer 20 mL of 0.5 M acetic acid (Ka is 1.75*10-5), stir at a slow setting and measure the pH reading is stabilized. Add 1.0 mL of 0.5 M NaOH and measure the pH. Continue adding 0.5 M NaOH in 0.5 - 1.0 mL increments until a major spike in pH occurs. After the spike, add another two 0.5 – 1.0 mL increments of 0.5 M NaOH. Create a pH vs. Volume graph to determine the range of the buffer’s capacity. Compare the actual data (nonstandard conditions) with the theoretical data under standard conditions. I NEED HELP WITH CALCULATIONS AN SMALL RESULT INTERPRETATION DESCRIPTION PLEASE TO UNDERSTAND WHAT I DID AND WHY THANKS
A 25.00 mL water sample required 14.00 mL of 0.021M EDTA to reach its endpoint. A blank titration required 2.13 mL. Calculate the hardness of the water sample in ppm CaCO3. Show the math setup.
Consider Table 1, which lists the volumes of the Fe3+ and SCN- solutions used for the continuous variation method. Note that each of the stock solutions is 0.002 M before mixing. What are the initial concentrations of Fe3+ and SCN- for solution 4, where the volumes are both 5 mL? [Initial meaning after they are mixed, but before]they reach equilibrium)
Pls help ASAP. Pls show all work and calculations.
Hi, Can I have your help on this problem. Thank you.
The KI used in this lab has a concentration of 0.500M. In trials 1-4, 1.0 ml of this solution is combined with 4.0 ml of the H2O2. What is the concentration of the KI in this solution after mixing but before the reaction occurs. ( Enter the result in table 1 on the report sheet) (2 sig figs)

Please show work and explanation on how to do it: A tums tablet pulverized (powdered) and 0.4265 g of this power was mixed with 9.00 mL 1.000 M HCl. This mixture was back titrated with 0.1000 M NaOH with phenolphthalein as indicator. It required 8.25 mL of 1000 M NaOH to reach the end point. Compute % CaCO3 in the tums sample and % error.
