Chapter 15: Q83E (page 877)

Question:Boric acid, H3BO3, is not a Br酶nsted-Lowry acid but a Lewis acid.

(a) Write an equation for its reaction with water.

(b) Predict the shape of the anion thus formed.

(c) What is the hybridization on the boron consistent with the shape you have predicted?

Short Answer

Expert verified
  2. The Lewis structure
  3. Since boron is attached to 4 atomic groups, the hybridization of it is sp3, and the shape is tetrahedral (because it is the most stable shape).

Step by step solution

01

predict the shape of the anion:

Boric acid (H3BO3 = B(OH)3)s a Lewis acid.

  1. Let us write an equation for the reaction between boric acid and water.


b. Let us predict the shape of the anion thus formed


c. Since boron is attached to 4 atomic groups, the hybridization of it is sp3, and the shape is tetrahedral (because it is the most stable shape).

Question: What are the concentrations of Ag+, CN鈥�, and Ag (CN)2鈭� in a saturated solution of AgCN?

The following question is taken from a Chemistry Advanced Placement Examination and is used with the permission of the Educational Testing Service. Solve the following problem:

MgF2 (S) 鈬� Mg2+(aq) + 2F- (aq)

In a saturated solution of MgF2 at 18 掳C, the concentration ofMg2+is 1.21脳10-3 M.

The equilibrium is represented by the preceding equation.

(a) Write the expression for the solubility-product constant, Ksp, and calculate its value at 18 掳C.

(b) Calculate the equilibrium concentration of Mg2+ in 1.000 L of saturated MgF2solution at 18 掳C to which 0.100 mol of solid KF has been added. The KF dissolves completely. Assume the volume change is negligible.

(c) Predict whether a precipitate of MgF颅2 will form whensolution of 100.0mL of a 3.00 脳10-3 -M Mg(NO3)2 is mixed with 200.0 mL of a 2.00 脳 10鈥�3 -M solution of NaF at 18 掳C. Show the calculations to support your prediction.

(d) At 27 掳C the concentration of Mg2+ in a saturated solution of MgF2 is 1.17脳10-3 M. Is the dissolving of MgF2 in water an endothermic or an exothermic process? Give an explanation to support your conclusion.

Question: Explain why addition of \(N{H_3}\;or\;HN{O_3}\) to a saturated solution of \(Cu{(OH)_2}\)in contact with solid \(Cu{(OH)_2}\) increases the solubility of the solid.

Calculate the concentration of PO43-when Ag3 PO4 starts to precipitate from a solution that is 0.0125M in Ag+.

Question: Under what circumstances, if any, does a sample of solid AgCl completely dissolve in pure water?
