Explanation:
Hello there!
In this case, for these problem about the colligative property of freezing point depression, it is possible set up the following equation:
Whereas the van't Hoff's factor, i, is 2 since KCl is ionized in two ions (K+ and Cl-); and the molality (m) of the solution is computed by:
Thus, since the freezing point of water (ice) is 0°C, we obtain the following freezing point of the solution by plugging in:
Best regards!
That is fine , you don't need to add anything else and you have given 3 supporting details
Answer:
the water has greater salinity
Explanation:
The term "Salinity" refers to the amount of salt present in water. Recall that the amount of solute increases when the volume of solution decreases. This is because the amount of substance present in a solution depends on the volume of the solution.
Hence, as water evaporates, the volume of the solution decreases and the salinity (amount of salt present) increases.
1)
HI(aq) → H⁺(aq) + I⁻(aq)
So this is an Arrhenius acid because it releases H⁺.
2)
LiOH(s) → Li⁺ + OH⁻
So this is an Arrhenius base because it releases OH⁻
