<h3><u>Answer;</u></h3>
the ions dissociate from each other in solution and are free to move independently
<h3><u>Explanation;</u></h3>
- <em><u>All soluble ionic compounds are strong electrolytes. They conduct very well because they provide a plentiful supply of ions in solution. That is; they mostly break up into ions as they dissolve in water</u></em>.
- An electrolyte solution conducts electricity because of the movement of ions in the solution.
- Ionic compounds have ions that are electrically charged to conduct electricity in liquid state or in aqueous solutions.
Hypochlourous acid only
Explanation : just is
The answer is true hope this helps
Answer:
Ka = 0.16
Explanation:
HClO₄ is a strong acid and it will dissociate completely to give hydrogen ion and the conjugate base.
The pH of HClO₄ will be calculated as:
pH = -log[H⁺]
pH = -log[0.04] = 1.4
The trichloroacetic acid is a weak acid and it will not dissociate completely.
The dissociation will be:
Initial 0.05 0 0
Change -x +x +x
Equilibrium 0.05-x x x
Ka = ![\frac{[H^{+}][ClO_{4}^{-}]}{[HClO_{4}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH%5E%7B%2B%7D%5D%5BClO_%7B4%7D%5E%7B-%7D%5D%7D%7B%5BHClO_%7B4%7D%5D%7D)
As pH of the acid = 1.4 it means the concentration of hydrogen ion is 0.04.
Therefore
x = 0.04
Putting values
Ka =
