Base:- A substance is called base if its aqueous solution tastes bitter, turns red litmus blue, or neutralizes acids. Salt:- Salt is a neutral substance whose aqueous solution does not affect litmus. What is the vocabulary of pH scale?The lower the number on the pH scale, the more acid a substance contains. The pH scale goes from 0 to 14, with 0 being the most acidic. The higher, low-acid numbers on the pH scale are basic — they feel slippery and have an astringent taste. Substances at around 7, the middle of the pH scale, are neutral, like water. How important it is to learn about acids bases and salts?Acids and bases are important to many chemical processes: maintaining a stable internal environment in the human body, baking a delicious cake, or determining whether a lake can support aquatic life. Reactions involving acids and bases can be described through the transfer of protons – single H+ ions. |
