What mass of oxygen is present in 10.0 grams of barium nitrate (Ba(NO3)2)?
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....
