Which one of the following statements is TRUE? Which one of the following statements is TRUE? A buffer can absorb an unlimited amount of acid or base. A buffer does not change pH when strong base is added. A buffer is an aqueous solution composed of two strong bases. A buffer resists pH change by neutralizing added acids and bases. None of the above are true.

 A buffer resists pH change by neutralizing added acids and bases.

Explanation:

Buffer is a solution which can resist the change in pH with small addition of acid or base.

Buffer solution is the solution which resists the change in the magnitude of the pH when small additions of either acid or base is adde. Buffer neutralises the added acid or base and hence prevent the change in pH.

Buffer solutions consist of weak acid and its conjugate base usually which are mixed in relatively equal and large quantities.

Two strong bases will not form a buffer.

Hence a buffer resists pH change by neutralizing added acids and bases.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
