Question

HELP!!!!

Answer 1

Because they are substances that give ions when dissolved in water. They can be divided into acids, bases, and salts, they conduct electricity due to the positive and negative ions, they are even called cations and anions.

Answer 2

Substances that give ions when dissolved in water are called electrolytes. Acids give out H+ while bases give out OH-

Answer 3

That is right dtan5457

Answer 4

Your answer is completely right, she wants you to show an ICE (initial, change, equilibrium) table

HA -> H^+ + A^-
I 0.5 M 0 0
C -0.0001 M +0.0001 M +0.0001 M
E 0.5-0.0001 M 0.0001 M 0.0001 M

so you plug the values from E into the equilibrium expression

\(K=\dfrac{[H^+][A^-]}{[HA]}=\dfrac{0.0001 M *0.0001 M }{0.5-0.0001 M}=\dfrac{{(0.0001 M) }^2}{0.4999M}\)

Answer 5

remember that the square brackets "[ ]" mean molarity "M"

Answer 6

So the units you're missing are in

here 1.0 x 10^-14 M^2

1.0x 10^-14 M^2
and here =------------
1 x 10^-11 M

Answer 7

Im not missing any unit for the 3??

Answer 8

nope, pH is unitless

Answer 9

Oh you're missing units here pH= -log[1 x 10^-3 M ]

Answer 10

Thats it?
