    Buffer solutions resist change in pH when a small amount of acid or alkali is added. This is because the buffer solution forms an equilibrium reaction.

    Buffer solutions are a solution of weak acid or alkali and its constituent salt.

    When acid is added, equilibrium position shifts to reduce the H+ concentration so to stop the pH decreasing (because more H+ means a smaller pH).

    When alkali is added, the system tries to counteract the change by increasing the concentration of H+ so to stop the pH increasing.

    I hope this isn't too jumbled
    Thank youuu
