A solution contains 1.46×10-2 M sodium fluoride and 1.48×10-2 M potassium carbonate. Solid magnesium acetate is added slowly to this mixture. What is the concentration of fluoride ion when carbonate ion begins to precipitate? [fluoride] = M
. The concentration of magnesium, calcium, and nickel(II) ions in an aqueous solution are 0.0010 M. (a) In what order to they precipitate when potassium hydroxide is added?; (b) determine the pH at which each salt will precipitate. The molarity of CrO42– in a saturated Tl2CrO4 solution is 6.3×10–5 mol·L–1, what is the Ksp of Tl2CrO4?

Which of the following solutions will have the highest concentration of fluoride ions? Which of the following solutions will have the highest concentration of fluoride ions? 0.10 M MgF2 0.10 M AlF3 0.10 M KF 0.05 M CaF2 All of these solutions have the same concentration of fluoride ions.
Na+=0.47 M, Mg2+=0.053 M, Ca2+=0.010 M magnesium is isolated from seawater by adding a strong base that cause the magnesium ions to precipitate. determine the minimum final hydroxide concentration that is needed to precipitate 99.9% of the magnesium ions from a sample of sea water at 25 C will any sodium ions ppt from seawater at the hydroxide ion concentration? will any calcium ions ppt from the seawater at hydroxide ion concentration ?
1. If Ksp = 6.4 x 10-9 for magnesium fluoride, what is the concentration of Mg2+ and Fin equilibrium with solid magnesium fluoride? First write the equilibrium expression for Ksp. 2. The concentration of Ag+ in a solution saturated with Ag2C2O4 is 2.42 x 10-4 M. Calculate Ksp for Ag2C2O4.
M. A student measures the Mg2+ concentration in a saturated aqueous solution of magnesium fluoride to be 1.15X10 Based on her data, the solubility product constant for magnesium Muoride is
What is the molar solubility of magnesium fluoride in a solution that is 0.40 M F− ions? The Ksp of MgF2 is 6.4 × 10−9. What is the molar solubility of magnesium fluoride in a solution that is ions? The Ksp of MgF2 is 6.4x10^-9 8.0 × 10−5 8.0 × 10−9 4.0 × 10−8 1.6 × 10−8
Magnesium ions move out of a cell through a transmembrane protein down (i.e. with) their concentration gradient. The energy harvested from this movement of magnesium ions is used to move sodium ions into the cell against their concentration gradient. This is an example of which type of transport? symport ABC transport antiport facilitated diffusion
