Question

A solution whose pH cannot be easily altered due
to accidental addition of acid or base is called
looma​

Answer 1

Answer:

Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions.

Explanation:

If you add a base to a buffer solution, the hydrogen ion concentration decreases by less than the amount expected for the quantity of base added. The acid and its conjugate base consume the hydroxide ions. The pH of the solution does not rise significantly, which it would do if the buffer system was not in use.
