2) You are tasked with determining the barium content of a sample containing barium nitrate mixed with rubidium nitrate. The sample is weighed, dissolved into 50.0mg water, and treated with xs 0.500M sodium sulfate. The acid fully ionizes in this experiment. A white precipitate forms which is washed, filtered, and weighed multiple times, according to the data given below: Mass of sample 0.425g Mass of thoroughly dried filter paper 1.462g Mass of precipitate+filter after 1st drying 1.755g Mass of precipitate+filter after 2nd drying 1.699g Mass of precipitate+filter after 3rd drying 1.698g B] What was the purpose of drying and weighing three times in succession?

Procedure: Step 1: Pipet 25 mL of prepared sample solution, which has been prepared into a 250 mL Erlenmeyer flask. Step 2: Add 3-5 drops of phenolphthalein indicator solution to the sample solution in the 250 mL Erlenmeyer flask. Step 3: Rinse the buret with three 10 mL portions of standardized 0.1 M HC1 acid solution, before fill this acid solution into the buret and record the initial volume of this acid solution in the burette. Step 4: Titrate the sample solution with the standardized 0.1 M HC1 to the endpoint and record the final volume of this acid in the burette. (Note: phenolphthalein endpoint is from pink color to colorless) Step 5: Repeat the titration for two more times. Step 6: Repeat the same procedure from step 1 to step 5 by using methyl orange as an indicator rather than phenolphathelein. (Note: methyl orange endpoint is from orange to red color). Calculate the alkalinity of the sample for both the indicators and potentiometric method using the following equation: [Alk]…
Six clean, dry, 18 x 150mm test tubes 1-6 was labeled. 5.00 L of 2.00 x 10-3 M Fe(NO3)3 solution was pipeted in each tubes. Then 1.00,2.00,3.00,4.00, and 5.00 mL of 2.00 x 10-3 M of 2.00 x 10-3 M NaSCN solution was then added to test tubes 2-6 respectively. 5.00, 4.00 ,3.00,2.00 and 1.00 mL of 0.10 M HNO3 was then further added to test tubes 1-6 respectively. The total volume in each test tube is 10 mL. a) what is the concentration of Fe(NO3)3 in 0.10 M HNO3? b) what is the concentration of NaSCN in 0.10 M HNO3 solution?

I had a 6.00 M NaOH solution and I diluted it to a 50mL solution of 0.300 M NaOh solution by adding 2.5 mL of NaOH and filled it up to the mark using DI water. I also had to make a 50mL of a 0.300 M NaCl solution by adding 0.8g of NaCl. I then pipet 20mL of the 0.300M NaOH solution into a small beaker and pipet 10.0mL of 0.300 M NaCl into it. What is the molarity/concentration of NaOH in the new solution I created by dilution? I need to use the formula M1V1=M2V2
Weigh out accurately 9.99 g of copper(II) sulfate pentahydrate (CuSO4·5H2O) by taring using a clean and dry empty 250-ml beaker. 2. Add tap water to the beaker to reach the 50-mL mark on the side of the beaker. 3. Dissolve all the crystals of CuSO4·5H2O in the water using a clean glass rod for stirring. 4. Then using a glass funnel transfer all the blue solution to a 100-mL volumetric flask. Rinse the beaker with about 10 mL of water and transfer the solution to the volumetric flask. Repeat the rinsing of the beaker with another 10 mL of water and transfer the solution to the volumetric flask. This is called quantitative transfer of the solution. 5. Then add enough water to reach the calibration mark of the volumetric flask. (You will need to use a dropper to add the last few drops of water to ensure the meniscus is on the calibration mark). Close the volumetric flask with a stopper and mix the solution well (so that it is homogeneous). 6. You have now prepared a standard solution (or…
