Acid Base Review

Acid Base Warm-Up

Quiz 5-1 is tomorrow (Tuesday)

K_w= 1 x 10^-14

If you know the constant of an acid or base, you can always calculate the constant of the conjugate!

K_a x K_b = K_w

Open Ended

HA has a K_a of 1.45 x 10^-3. What is the conjugate base and it's K_b value?

Ex. sodium cyanide

Salts from weak acids and bases will have an effect on pH

Ex. potassium chloride (HCl & KOH)

The salt from a strong ​acid and a strong base is neutral
