Calculate the molar solubility of ca(io3)2 in each solution below. the ksp of calcium iodate is7.1 × 10−7.
e-lub [12.9K]
In order to find the answer, use an ICE chart:

Ca(IO3)2...Ca2+......IO3- 
<span>some.......0..........0 </span>
<span>less.......+x......+2x </span>
<span>less........x.........2x 
</span>
<span>Ca(IO₃)₂ ⇄ Ca⁺² + 2 IO⁻³
</span>
K sp = [Ca⁺²][IO₃⁻]²
K sp = (x) (2 x)² = 4 x³
7.1 x 10⁻⁷ = 4 x³
<span>x = molar solubility = 5.6 x 10</span>⁻³ M

The answer is 5.6 x 10 ^ 3 M. (molar solubility)

What is the periodic table, and what is its significance in the study of chemistry?
NeX [460]

Explanation:

<u>Periodic table is the tabular display of elements that are arranged by the increasing atomic number. </u>

Structure of the periodic table shows various periodic trends.

<u>Significance: </u>

The periodic table is very important because it gives an organized way to provide lots of information about the elements and how they can be related to one another. The table gives a systematic approach to study the elements and their properties. The table can also be used to predict the properties of the elements which have not been discovered yet.
