Based on the freezing point depression value of HCl in benzene, HCl does not act as an electrolyte in benzene.
<h3>What is the effect of solute on the freezing point of a solvent?</h3>
The freezing point of a solvent such as water is lowered by the solute which ionizes in it.
The freezing point of a solution depends on the number of particles in the solution.
The formula for freezing point depression is given below:
ΔTf = i * Kf * m
HCl remains as molecules and does not ionize in a solution of Benzene. This is because benzene is a nonpolar solvent.
Therefore, the equation for the dissolution of HCl in benzene is given below:
HCl (g) → HCl (in benzene solution)
1 mol of HCl gas gives 1 mol of HCl molecules in solution.
Therefore, HCl remains a molecule and does not act as an electrolyte in benzene.

The pH of a solution is a measure used to evaluate the acidity of a solution. It is related to the hydronium ion concentration in the solution. It is expressed as pH = -log [H+]. Also, it is related to pOH by the equation 14 = pH + pOH. It is stated that the substance given in the problem is a strong base which means that it completely dissociates into ions. It dissociates as follows:
Ba(OH)2 = Ba^2+ + 2OH-
To determine the pH of the solution, we need to determine the OH- concentration. Then, find pOH. We do as follows:
[OH-] = 0.0064 mol Ba(OH)2 / L ( 2 mol OH- / 1 mol Ba(OH)2 ) = 0.0128 mol OH- / L
pOH = -log (0.0128) = 1.8928
pH = 14 - 1.8928 = 12.1072
Answer:
See explaination
Explanation:
Please kindly check attachment for the step by step solution of the given problem.
Answer:
A
Explanation:
Because total energy is always constant, it only changes form but energy is never destroyed nor created. This is 1st law of thermodynamics which is basically principle of conservation of energy.
Hope this helps!
