Calculate the pOH of a salt solution formed by mixing a weak acid and a strong base.

• The pOH of the salt solution cannot be determined without additional information such as the identity and concentration of the weak acid and strong base used.

• The pOH of the salt solution is equal to the pH of the weak acid

• The pOH of the salt solution is always 7

• The pOH of the salt solution is equal to the pKa of the weak acid

What is the pH of a salt solution formed by mixing a strong acid and a weak base?

• The pH will always be neutral.

• The pH will be basic.

• It depends on the relative strengths of the acid and base.

• The pH will be acidic.

Calculate the pOH of a salt solution formed by mixing a weak acid and a weak base.

• pOH = -log[acid]

• pOH = -log[H+]

• pOH = -log[OH-]

• pOH = -log[salt]
