Q

Kb vs Ka

A

Base ionization constant and acid ionization constant

17
Q

Strong electrolytes

A

Solutes that completely dissociates into ions when dissolved in water

18
Q

Non-electrolytes

A

Solutes that dissolve in water without separating and ions

19
Q

[OH]=Kw/[H3O]

What is Kw

A

1.0x10^-14

20
Q

Since a strong acid like hydrochloric acid is completely dissociated in aqueous solution the solution of the acid tells us what

A

The number of hydronium ions present

.1M of HCl completely dissociates so the concentration of H3O+ is .1M

21
Q

What forms when you mix a strong acid in a strong base

A

Water and salt

22
Q

Result of a reaction of an acid with a bicarbonate or carbonate

A

The acid and base react to form a salt and carbonic acid which decomposes to CO2 and water
