Answer: The freezing point and boiling point of the solution are and
respectively.
Explanation:
Depression in freezing point:
where,
= freezing point of solution = ?
= freezing point of water =
= freezing point constant of water =
i = vant hoff factor = 1 ( for non electrolytes)
m = molality
= mass of solute (ethylene glycol) = 21.4 g
= mass of solvent (water) =
= molar mass of solute (ethylene glycol) = 62g/mol
Now put all the given values in the above formula, we get:
Therefore,the freezing point of the solution is
Elevation in boiling point :
where,
= boiling point of solution = ?
= boiling point of water =
= boiling point constant of water =
i = vant hoff factor = 1 ( for non electrolytes)
m = molality
= mass of solute (ethylene glycol) = 21.4 g
= mass of solvent (water) =
= molar mass of solute (ethylene glycol) = 62g/mol
Now put all the given values in the above formula, we get:
Thus the boiling point of the solution is
<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>
<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>
<em>• Sulfurous acid if [H +] = 0.10 </em>
<em>• Nitric acid if [H +] = 0.11</em>
<em />
<h3>Further explanation </h3>pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
- pH acid rain
- pH Sulfurous acid
- pH Nitric acid
