What is the molecular polarity of calcium hydroxide
1 answer:
Answer:Calcium hydroxide is a polar compound. 2. Carbonates are insoluble in water unless it is combined with NH4+ or any group 1A ion. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water.Ca(OH)2 is an ionic compound, in which Ca is the cation and OH is the anion. Ca (calcium) has a charge of 2+, since it is in group 2 on the periodic table.

Explanation:
In the box on the left there are 8 Cl⁻ ions and 8 Na⁺ ions.
The dissociaton equation for NaCl(aq) is:
- NaCl (aq) → Na⁺ (aq) + Cl⁻(aq)
The dissociation equation for CaCl₂ (aq) is:
- CaCl₂ (aq) → Ca²⁺ (aq) + 2Cl⁻(aq)
A 0.10MCaCl₂ (aq) solution will have half the number of CaCl₂ units as the number of NaCl units in a 0.20M NaCl (aq) solution.
Thus, while the 0.20M NaCl (aq) solution yields 8 ions of Na⁺ and 8 ions of Cl⁻, the 0.10MCaCl₂ (aq) solution will yield 4 ions of Ca²⁺ (half because the concentration if half) and 8 ions of Cl⁻ (first take half and then multiply by 2 because the dissociation reaction).
Thus, your drawing must show 4 dots representing Ca²⁺ ions and 8 dots representing Cl⁻ ions in the box on the right.
