Answer:
Sodium hydroxide solution.
Explanation:
because it is a strong base. Since carbonic acid is a weak acid, a solution formed resists change in pH on addition hence buffer formed.
Sodium hydroxide solution can be can be mixed in solution with H2CO3 to make a buffer.
What is buffer?
A buffer would be a solution that could withstand pH changes when acidic as well as basic components are added.
What is solution ?
The term "solution" was most frequently associated with the liquid form of matter, however gases as well as solids can also form solutions.
A traditional buffer is made up of a weak acid including its conjugate salts, such as carbonic acid (H2CO3) as well as sodium bicarbonate (NaHCO3) or sodium bicarbonate with calcium carbonate.
