Why can ionic compounds Conduct electricity ?

1 answer:

katen-ka-za [31]2 years ago

4 0

Explanation:

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

What is the pH of a solution of KOH with a hydroxide concentration of [OH⁻] = 1.10 x 10⁻⁴

olga2289 [7]

Answer:

$p[H+] = 10.042$

Explanation:

As we know that

$pKw = pH + pOH$ ......eq (1)

we will calculate the pH of OH- and then we will calculate the pH of H+

So p[OH-] $= - log [1.10 * 10^{-4}]$

Solving the right side of the equation, we get

p[OH-]

$= - [-3.958]\\= 3.958$

Now we know that

$pKw = 14.0$

Substituting the value of pOH in the above equation, we get -

$14.0 = p[H+] + 3.958\\p[H+] = 14 - 3.958\\p[H+] = 10.042$
