Answer: The molarity of solution is 3.37 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute = 0.614
= volume of solution in ml = 182 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution is 3.37 M
<u>Ques</u><u>tion</u><u>:</u>
How are changes of state different from chemical change?
<u>Answer</u><u>:</u>
Physical changes alter only the size, shape, form or matter state of a material. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes.
On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed.
Strong solute-solvent attractions increase solubility of ionic compounds. Ionic compounds are most soluble in polar solvents like water, because the ions of the solid are strongly attracted to the polar solvent molecules.
COMMON-ION EFFECT
Ionic compounds are less soluble is solvents that contain a common ion. For example, CaSO₄ is slightly soluble in water.
CaSO₄(s) ⇌ Ca²⁺(aq) + SO₄²⁻(aq)
If the water already contains calcium ions or sulfate ions, the position of equilibrium moves to the left and the solubility decreases (Le Châtelier’s Principle).
TEMPERATURE
Increasing the temperature usually increases the solubility of an ionic compound because the solution process is usually endothermic.
CaSO₄(s) + heat ⇌ Ca²⁺(aq) + SO₄²⁻(aq)
Le Châtelier’s Principle predicts that increasing the temperature (adding heat) will shift the position of equilibrium to the right. The compound will become more soluble. From a webpage i found this from https://socratic.org/questions/what-factors-affect-solubility-of-ionic-compounds
