essay on acid and base
Answers
Answer:
I found out that the hydrochloric acid produced by the stomach is a very strong acid. Acids taste sour, change litmus red, and become less acidic when mixed with bases. A base is a substance that has a pH value of more than 7. The definition of a base is a compound that produces hydroxide ions in solution
Here is your answer
i hope it will help you
Acid and bases are very important in our everyday activity. Almost every liquid you find is acid or bases but it is not just liquid you can find it almost everywhere. Both are used in our usual activity especially in our body. They have a variety of uses like in medicine, food, cleaning, fertilization, industry and as I mentioned before they are used in our body so it allow it to function properly.
Acid is a substance that produces hydrogen ions (H+) in water solution. (1) The ability to produce theses ions give acid their unique property that they have. (1) It is also a substance that have a PH less than 7 when it is seven that mean it is neutral .(2) A PH scale is a scale that show acidic or basic a solution is. (2) .The more a substance is acidic then that means the lower its PH is. (2) for example we have lemon juice that have citric acid and ascorbic acid which is vitamin C, lemon have a PH of two which mean it is acidic. (2) There is an organic substance that is called indicator that changes color when it touches an acid or a base. (1) An example of this organic substance is blue litmus paper that turns red in acid. (1) There are many types of acids like hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, etc. (3) When some acid is intact with metal it sometimes react strongly which eat it away as metallic compound and hydrogen gas form, acids also donate H+ and its solution can transfer/move electricity. (1) Also is have a sour taste and when it react with base it give us salt and water. (1) Give sharp stinging pain when put on a cut or wound. (4)
Bases are a substance that produces hydroxide ions when it dissolves in water. (1) It is considered any substance that accepts (H+) from acids. (1) When acids donate H+ the one to take them is bases in other world both are complement to each other. (1) Of course that is not all; bases have a lot of property. For example it feel slippery this feeling is caused because when it touch your skin it to dissolve a little bit, taste bitter, react with oils and greases, and it is frequently solids.(5) When the PH is above seven that mean that it is a base.(5) It also cause red litmus indicator to turn blue and its solution can transfer electricity. (6)There are a lot of types of bases like aluminum hydroxide, calcium hydroxide, ammonia, etc. (1)
As you know in the blood you have acid and bases and there are mechanisms in our body that control the balance between acid and bases. (7) The one in charge in controlling the blood PH are the lungs and the kidney. (7) The lungs can increase the blood PH by releasing higher amount of carbon dioxide than usually. (7) As you know carbon dioxide is mildly acidic which cause the acidity of the blood to increase in the lungs the things that affect the increase of PH in blood are depth and speed of breathing.(7) We also have the kidney that helps control the acids and bases by regulating their release but it take more time for it to regulate the PH than the lungs because it release bases and acid in minute amount. (7) In out body there is a place where you can find acid (HCl) which is found in the stomach. There is also the Buffer system that contain weak bases and the weak acids that form naturally in the body but once the balance is broke and incline toward one of them, the weaker one start to excreting correspondingly and as a result of that it become balanced again there are two things that help the buffer system which are carbonic acid and bicarbonate ions. (7)
Acid and bases can be found also at our houses. They can be found in food, cleaning fluid, etc. At home they are of a great use in mostly cleaning and food. In case of food we have these which are acids: vinegar, soda, beer, lemons, grapefruits, tomatoes, etc. (8) anything from a citric fruit contains citric acid which is weak, the vinegar contains acetic acid which is strong, in soda it contain carbonic acid which is weak. We also have batteries that contain sulfuric acid. (9) In case of household bases we have antacids, milk of magnesia, ammonia, drain openers, baking soda, soap, oven cleaners and detergents. (9) Baking soda contains sodium hydrogen carbonate which is base, ammonia (NH3) is found in some cleaners, soap have potassium hydroxide, oven cleaners contain sodium hydroxide. (7)
We can also find acid and bases in agriculture which is used to grow plant. The effect of acid and base on plants varies, depending on the concentration they may improve the plant health or damage it.
