QUESTION 1 Which best describes why the neutralization of a weak acid with a strong base produces a solution which is basic. O A This is a result of the acid and base not reacting to completion and therefore some weak acid remains. O B. This is a result of the acid and base not reacting to completion and therefore some strong base remains O C. This is a result of a salt containing a weák base being produced. D. This is a result of the base in the reaction being stronger than the acid. QUESTION 2 Will an aqueous solution of KBr be acidic, basic or neutral? 0 A basic O B neutral O C acidic QUESTION 3 How does ionization take place with polyprotic acids? O A All of the protons ionize from the acid all at once. O B. The ionization is a stepwise process. O C. Two protons ionize in one step. C D. Three protons ionize in one step

Explanation / Answer

1)

strong base and weak acid reacts to form salt which is basic in nature. This salt is strong base

This is the reason for basic nature of solution

Answer: D

2)

KBr is salt of Strong base (KOH) and Strong acid (HBr)

Both acid and base are strong

So, the salt KBr is neutral

3)

H+ are removed step by step from polyprotic acid

Answer: B
