Answered step-by-step

Problem 164 Hard Difficulty

Referring to the Chemistry in Action essay on page 156, answer the following questions: (a) Identify the precipitation, acid-base, and redox processes. (b) Instead of calcium oxide, why don't we simply add sodium hydroxide to seawater to precipitate magnesium hydroxide? (c) Sometimes a mineral called dolomite (a mixture of $\mathrm{CaCO}_{3}$ and $\mathrm{MgCO}_{3}$ ) is substituted for limestone to bring about the precipitation of magnesium hydroxide. What is the advantage of using dolomite?

Properties Of Solutions - Intro

In chemistry, a solution is a homogeneous mixture composed of two or more substances. The term "solution" is also used to refer to the resultant mixture. The solution is usually a fluid. The particles of a solute are dispersed or dissolved in the solvent. The resulting solution is also called the solvent. The solvent is the continuous phase.

Aqueous Ionic Equilibrium - Intro

In chemistry, an ion is an atom or molecule that has a non-zero net electric charge. The name was coined by John Dalton for ions in 1808, and later expanded to include molecules in 1834.

Okay for 1642 and 64, yes, 164. First, a the recipitation reaction; magnesium tis, not his own water. The acid base reaction, okay in this preduce traction aso, with a total reaction like this okay. So in this only i got to be sodium hydroxide of space than casum sophy casum sophy going cassian, the that's very cheap okay and we we 1000 shares a degree we can let see- and to this is very keep my spencyespency, then c, a o okay and See the advantage, but his additional shock, nanase merapi, that additional shaft of the vantage.
