A saturated solution of lead(II) iodide, PbI2 has an iodide concentration of 3.0 x 10^-3 mol/L. a) What is the molar solubility of PbI2? b) Determine the solubility constant, Ksp, for lead(II) iodide. c) Does the molar solubility of lead (II) iodide increase, decrease, or remain unchanged with the addition of potassium iodide to the solution? EXPLAIN.
A student adds 0.0035 mol of NaF to 1.00 L of 0.02 M barium nitrate, Ba(NO3)2. Which of the following statements is correct? Ksp = 1.5 × 10–6 for BaF2. Assume there is no volume change upon addition of NaF. One must know Ksp for barium nitrate to make a determination Barium fluoride precipitates until the solution is saturated. The solution is unsaturated and no precipitate forms. The solubility of barium fluoride is increased upon the addition of fluoride ions....
Ksp of PbCO3=1.5 x 10^-13 CaCrO4 7.1 × 10-4 The mass of lead carbonate that is dissolved in 150 mL of a saturated solution is | grams. The volume of water needed to dissolve 0.0606 grams of calcium chromate is 0.014 L. Assume no volume change upon addition of the solid.
1- A saturated solution of lead(II) iodide, PbI2 has an iodide concentration of 3.0*10^-3 mol/L. a- What is the molar solubility of PbI2? b- Determine the solubility constant, Ksp for lead (II) iodide. c- Does the molar solubility of lead(II) iodide increase, decrease or remain unchanged with the addition of potassium iodide to the solution? Explain? 2- The Ksp of Ca(OH)2 was 5.2*10^-6 and 4.8*10^-6 respectively. a- What is the average Ksp of Ca(OH)2?
question#1 Experiment 17A. A Solubility Product Constant Procedure Getting Started 1. Obtain a 10 ml pipet, a 50 mL buret, and 2 pieces of 120 cm filter paper Preparing Saturated Solutions of M10J MIO), is an insoluble divalent iodate salt. The identity of the cation M-is unknown. 1 Prepare MIO,), by adding S0 ml of o.2 M KIO, to 20 mL of 1 Molar M(NO,J, in a 150 mt 2. Stir the mixture vigorously with a stirring rod. A white,...
Directions: Please complete Prelecture Assignment and upload answers to Carmen as a PDF before coming to lecture. Before attempting this worksheet, please read Lab 8 as this worksheet accompanies the lab and helps you get your lab notebook ready by guiding you through the necessary calculations that will be needed to start the experiment. This lab takes more thought and effort to set-up, but faster to complete if you think about things now. Please bring a copy of the completed...
PartA: Penny-→ Cu2+(aq) Make sure it is dated prior to 1982. Record mass to nearest 0.001 I. Weigh a copper penny. grams. 2. Place 450 mL of distilled water in a clean 600-mL beaker. Place the beaker on a hotplate and heat until the water boils. Do not wait for the water to boil now, but proceed with the rest of the experiment. You will need this water for rinsing in step C3. CAUTION. You will generate poison°แs nitrogen dioxide...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...
