Calculate the concentration (molarity) of Pb2+ ions in a solution made by adding 0.010 moles of Pb(NO3)2 to 1.0 L of a  2.0 M NaI solution.  (Kf = 3.0 x 104 for PbI42−) - 4.9 x 10−2 -3.3 x 10−5 - 2.1 x 10−7 -1.7 x 10−7 -2.3 x 10−8

Barium sulfate is a contrast agent for X-ray scans that are most often associated with the gastrointestinal tract. Calculate the mass of BaSO4that can dissolve in 100.0 mL of solution. The Ksp value for BaSO4is 1.5 × 10−9.

Question 25 of 30 Submit You prepare a standard NAOH solution for the laboratory, using potassium hydrogen phthalate (KHC§H,0a, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/ mol) has one acidic hydrogen. It took 31.55 mL of the NaOH solution to titrate (react exactly with) 0.750 g KHP. You then use the standard base solution to determine the amount of ascorbic acid in a 500.0 mg tablet of vitamin C. Ascorbic acid (HC6H,O6, molar mass 176.12 g/mol) also has one acidic hydrogen, and is usually mixed with some filler in preparing the tablets. It requires 19.74 mL of the NaOH to titrate (react exactly with) | % 1 4 6. C 7 +/- x 10 0 Tap here or pull up for additional resources LO 00

The composition of a hydrated sodium-salt of a chromium(III)-oxalate complex ion conforms to the general formula: NaxCr(C2O4)3·wH2O A 0.2547-g sample of this compound required 21.99 mL of 0.02925 M KMnO4 solution for the titration of all of the oxalate. a)What is the value of x? b)What is the value of w?
