if 0.200 L of 0.24 M Ca(NO3)2 and 0.300 L of 0.043 M Na2CrO4 are mixed, what is the Qip? The Ksp for CaCrO4(s) = 7.1x10^-4

A 12.7g sample of vinegar is titrated.  It requires 19.75 mL of 0.205 M NaOH to neutralize the acetic acid (CH3COOH) in the vinegar.  Calculate the weight percent (w/w) of acetic acid in the vinegar.  Note: 1 mole of base neutralizes 1 mole of acid.

Pseudogoutis caused by the formation of calcium diphosphate (Ca2P2O7) crystals in tendons, cartilage and ligaments, usually occurring if diphosphate levels in blood plasma 7   become very If the [Ca2+] in blood plasma is 9.2 mg/dL and Ksp for Ca2P2O7 is 8.64 x 10-13, what is the minimum concentration of diphosphate P2O 4- necessary for precipitation?

At a certain temperature lead(II) fluoride has a Ksp = 1.09×10-7. What is the solubility of lead(II) fluoride in a 0.500 M sodium fluoride solution? Solubility of lead(II) fluoride =  _____ g/L

An impure sample of 250 mg of adipic acid was recrystallized from 2.0 mL of boiling water. The solution was cooled to room temperature slowly and further cooled in an ice bath. What is the maximum amount of recoverable adipic acid at 0 oC? Solubility of adipic acid at 0 oC is 0.3 g/ 100 mL Group of answer choices 6 mg 249 mg 244 mg 250 mg

Question 4 Three students studied the following solubility curve. They were asked to determine the 160 KNO, amount of NH,CI that needs to be added to 58 g NH CI to create a saturated solution at 140 NaNO 80°C. 120 100 KBr Student 1 said 25 g more would need to be added, student 2 said 22 g and student 3 said 17g NH CI needs to be added. NH C NaCi Which student is correct? Provide 20 evidence from the solubility curve to support your claim. 10 20 30 40 50 60 Temperature ("C) 70 80 90 Solubility (g/100 g H,0)

At a certain temperature, 6.8 x 10-4 grams of CoCO3 are found to dissolve in 113.6 mL of water to form a saturated solution. What is the value of Ksp for CoCO3 at this temperature? The molar mass of CoCO3 is 118.941 g/mol.

Siven that the solubility of NaCl is 35.7 g/100 mL solution, calculate the 'accepted" value of the Ksp of NaCl.

A solution contains S 2– and SO 42– ions. In what order dowe add Ag(NO 3 )(aq) and Ba(NO 3) 2(aq) to separate eachanion independently? Which precipitates form?

If a student combines specific amount CaCl2. 9H2O and Na2CO3 and obtained a solid precipitate. The student dissolve 1.37 gram of CaCl2. 9H2O in 25.0 mL of water and 0.984 g of Na2CO3 in 25.0 mL of water.  The student is then combining the two solutions and observed the formation of a solid precipitate. The student filter the solution and recovered the precipitate. The following data were obtained for the experiment.   Initial Mass of CaCl2. 9H2O 1.37 g    Initial Mass of Na2CO3 0.984 g % yield of this experiment 87.4% 1. What is the balanced equation for this experiment?
