Answer</h2>
Buffer controls the sudden change in the solution
<h2>
Explanation</h2>
Buffer prevents the sudden change in the pH. They keep the pH of the solution nearly constant. For example, in human Buffer solution helps to regulate the pH of human blood. The normal pH of the human blood is nearly 7.35 to 7.45 and a little change in this pH many leads the serious problems. Carbonic and bicarbonate buffers play a role in maintaining the acid base balance of the blood.
Increased atmospheric carbon dioxide will diffuse to the ocean water (since normally, there is lower concentration of dissolved carbon dioxide in the ocean water). The dissolved carbon dioxide takes into the form of carbonic acid thereby increasing acidity of ocean water. More often than not, the acidification of ocean water leads to detrimental results especially in marine organisms that are pH sensitive such as coral reefs and many invertebrates.
If a chromatographic column is not placed in a vertical position, the flow and the separation rate of the materials which are been separated may be negatively affected, that is, it may be slowed down, this is because the column is not inclined in the same direction as the flow of the separating substances. Also, collecting the products of the separation will be a bit difficult. If the column is placed in a vertical position, then a test tube can be placed at the end of the column for collecting the separated product
