WebB. What effect on the molar mass of the unknown acid would each of the following have-that is-would it make the calculated molar mass high, low, or would it have no effect. 1. Adding 5 drops of phenolphthalein instead of 1 drop. 1. _____ 2. Using a standard NaOH solution that has been left 2. _____ unstoppered for several days. Explain: 3. WebHomework help starts here! Science Chemistry 100.0 mL of HCl required 5.831 g Mg (OH)2 to titrate. The molar mass of Mg (OH)2 is 58.31 g. What is the concentration of the HCI ? The neutralization equation is 2 HCI + Mg (OH)₂ → MgCl₂ + 2 H₂O There is enough information to calculate the moles of Mg (OH)2 mol Mg (OH)2 (5.831 g Mg (OH)2 ...

WebMolar mass of the triglyceride: Molar mass of the sodium carboxylate salt formed: Mol of NaOH used in the procedure (see Part 1, Step 2) Mass of watch glass + filter paper + soap: Mass of watch glass + filter paper: Mass of soap produced: Oil used (canola or coconut): Canola Oil (Treat as triglyceride with 3 linoleic acid molecules) 878.57g/mol 302.45g/mol … WebAug 4, 2024 · The molarity and volume of NaOH allow anyone to determine how many moles of NaOH is used to neutralize the same number of moles of hydrated protons H3O+. Moles of NaOH = (0.1.05 moles NaOH / liter of solution)(0.0321 liters of solution) = 3.37x10^-3 moles NaOH used ... The molar mass of the diprotic acid is the ratio of the … the parklands ln2
Acid Base Titration Determination of the Purity of KHP …
Weba) Determine the percent of potassium acid phthalate (KHP) in an unknown sample by means of an acid base titration with NaOH. b) To standardize a sodium hydroxide solution with potassium hydrogen phthalate. c) To determine the molar concentration and mass/mass percent concentration of acetic acid in an unknown vinegar solution. WebQuestion: Aqueous sulfuric acid (H2SO4) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium sulfate (Na2SO4) and liquid water (H2O) . Suppose 73.6 g of sulfuric acid is mixed with 84. g of sodium hydroxide. Calculate the maximum mass of sodium sulfate that could be produced by the chemical reaction. WebThen to determine the molar mass, the calculation is as follows: 7.72 g HA 1L soln L soln 0.12 mol = 64.33 mol 64-8 HA A technique known as half-titration can now be used to determine the pk of the weak acid. In this experiment, the half-titration point will exist when you have added half the volume of NaOH needed to fully titrate the acid. the parkland shooting shooter
