Question

question 3
what was the result of adding a base such as naoh to the buffered solution?
it became acidic
it became exceedingly alkaline
there was minimal or almost no change.
question 4
a buffer resists dramatic changes in ph.
true
false
question 5
non metals are good at forming covalent bonds.
true
false

Explanation:

• Question 3: A buffer solution resists changes in pH upon addition of small amounts of acid or base. Adding a base like NaOH to a buffered solution will cause minimal or almost no change in pH as the buffer components react with the added base.
• Question 4: By definition, a buffer resists dramatic changes in pH by reacting with added acids or bases.
• Question 5: Non - metals have high electronegativities and tend to share electrons to achieve a stable electron configuration, making them good at forming covalent bonds.

Answer:

• Question 3: There was minimal or almost no change.
• Question 4: True
• Question 5: True
