# how to find molar solubility

3) Determine [Ba 2+] and [PO 4 3 ¯]: Example 1. ? The formula for K sp is: K sp = [Ag + ] [I –] K sp = s 2 = 8.5 x 10 -17. where s is the concentration of each ion at equilibrium. Calculate the molar solubility of Fe(OH)2 when buffered at pH = 10.1. An example of an insoluble substance, AgBr (silver bromide), has a minuscule molar solubility with the value being close to 5.71 x 10 to the … moles of solute in 100 mL; S = 0.0016 g / 78.1 g/mol = $$2.05 \times 10^{-5}$$ mol $S = \dfrac{2.05 \times 10^{ –5} mol}{0.100\; L} = 2.05 \times 10^{-4} M$ even though it is immportant ffor calculating Ka and Kb. Example #1: Silver chloride, AgCl, has a K sp = 1.77 x 10¯ 10. The molar solubility of AgI is 9.0 x 10 -9 mol/L. What is the molar solubility of MgF 2 in a 0.20 M solution of NaF? It is a constant property of each substance - for example, the molar mass of water is approximately equal to 18 g/mol. Solution. But we have [OH-]= 1.26 x 10^-4 M so at equilibrium: Ksp = manufactured from the ions. Use the ksp value and [OH-] above to find [Fe+2].

I thought I knew how to work them but keep coming up with the wrong answer for both. Calculate the K sp for Ba 3 (PO 4) 2. Join Yahoo Answers and get 100 points today. I went to a Thanksgiving dinner with over 100 guests. Example #10: The molar solubility of Ba 3 (PO 4) 2 is 8.89 x 10¯ 9 M in pure water. K sp (MgF 2) = 8.0 x 10-8.. I thought I knew how to work them but keep coming up with the wrong answer for both. The solubility of barium sulphate at 298 K is 1.05 x 10-5 mol dm-3. a.) calculate the molar solubility of Ag2CrO4 AT 25 C in: a- pure water b- 0.200M AgNO3 C- 0.200M Na2CrO4 for Ag2CrO4 AT 25C, Ksp=1.2x10^(-12) Which of the following compounds is most soluble in water? Still have questions? Draw structures of OF2, BrF3, SCl2, XeF4, PF3 in a way that indicates their molecular shape? It is expressed in grams per mole. Should I call the police on then? pOH = - log[OH-] = 3.9 to find conc. Molar solubility (M) is a measure of the ability of a compound, called a solute, to dissolve in a specific substance, called a solvent.Specifically, it is the maximum number of moles of a solute that are able to dissolve in one liter of solvent, so molar solubility is measures as moles/L. The solubility of CaF 2 (molar mass 78.1) at 18°C is reported to be 1.6 mg per 100 mL of water. Solution: 1) Write the chemical equation for the dissolving of barium phosphate in water: Ba 3 (PO 4) 2 (s) ⇌ 3Ba 2+ (aq) + 2PO 4 3 ¯(aq) 2) Write the K sp expression for barium phosphate: K sp = [Ba 2+] 3 [PO 4 3 ¯] 2. If 50.0 mL of 0.540 mol/L sodium hydroxide reacts with 85.6 mL of sulfuric acid, calculate the concentration of the sulfuric acid. An example of a soluble substance is NaNO 3 (sodium nitrate), which has a high molar solubility with 10.0+ moles per liter of solution most of the time. I thought I knew how to work them but keep coming up with the wrong answer for both. Calculate the molar solubility of Fe(OH)2 when buffered at pH = 10.1. well assuming that the value of 0.01835 M ( 1.835 X 10^-2 M ) is the correct and represents the amount of Ca(OH)2 in a std solution ..then the formal solubility is 1.835 x 10^-2 M..the amount of Ca+2 is 1.835 X 10^-2 M, the amount of OH^-1 = 3.67 x 10^-2 M, the solubility … Molar mass is the mass of 1 mole of the solute.
