- Which of the following is true when preparing solutions? a. Make sure that the solvent and reagents are contaminated. b. When diluting to the mark using a volumetric flask, the upper meniscus and mark should be at eye level. c. If amount added is over the mark, you cannot just take out the excess liquid and preparation must be repeated. d. After mixing the contents of the flask and the level of the meniscus seems lower than the mark, add more diluent.I need help with filling out the accompanying chart. Here is the data provided: Part A: The standardized HCl solution being used is 0.198 M. Trial 1: Using a volumetric pipette, you pipet exactly 20.00mL of the standardized HCl solution into a 250-mL Erlenmeyer flask. You then add 2-3 drops of phenolphthalein. Trial 2: Using a volumetric pipette, you pipet exactly 10.00mL of the standardized HCl solution into a 250-mL Erlenmeyer flask. You then add 2-3 drops of phenolphthalein. Trial 3: Using a volumetric pipette, you pipet exactly 10.00mL of the standardized HCl solution into a 250-mL Erlenmeyer flask. You then add 2-3 drops of phenolphthalein. Trial B: Determining the molarity (M) of acetic acid in vinegar. Trial 1: Using a volumetric pipette, you pipet exactly 5.00mL of the vinegar solution into a 250-mL Erlenmeyer flask.

- Calculate how much by volume of each concentrated stock solution you will need. Your starting materials are 1M HEPES 1 M midsole and 5 M salt.B and C..... please show step by step solutionCalculate how many grams of phthalic acid remained in the chilled water (the “mother liquor”) based on the solubility data given (show your work). You will recrystallize phthalic acid, a compound that is used to manufacture synthetic polymers and perfumes. Phthalic acid is very soluble in boiling water, 18 g/100 mL, and is much less soluble in chilled (14°C) water, 0.54 g/100 mL. Thus, water is a very good recrystallization solvent for phthalic acid. 54.8% percent recovery was calculated
