State Differences between Acids and Bases?
The difference between acids and bases are as follows
| ACIDS | BASES |
| A chemical compound with a sour taste is known as an acid. | A chemical compound that has a harsh taste and feels soapy to the touch is known as bases. Bases are also called alkaline. |
| Substances that contain acid are known as acidic substances. | Substances that include a base are known as basic substances. |
| When dissolved in water, hydrogen ion (H+) is produced. | When dissolved in water, hydroxyl is (OH–) is produced. |
| Acid turns blue litmus paper to red. | The base turns red litmus paper to blue. |
| Phenolphthalein remains colourless in acid. | Bases give a pink colour in Phenolphthalein. |
| Acid turns Methyl Orange from yellow to a dark red colour. | On base, Methyl Orange remains yellow. |
| It has a pH value lower than 7. | It has a pH value higher than 7. |
| The strength of Acid depends on the concentration of hydrogen ions. | The strength of the base depends on the concentration of hydroxide ions. |
| Acid react with bases to form salts. | Bases react with acids to form salts. |
| Acids are generally found in vinegar, lemon, spinach, curd, tamarind, citrus fruits such as oranges, grapes, amla, unripe mangoes, etc. | Bases are generally found in different substances such as ammonia, soap, washing powder, lime water, bleach, window cleaner, Milk of Magnesia. |
| Acids are used in carbonated drinks, in car batteries, as a cleaning agent. | Bases are used in detergents, in soaps, as an antacid. |
Examples are: – H2SO4 (Sulphuric Acid) HCl (Hydrochloric Acid) H2CO3 (Carbonic Acid) | Examples are: – NaOH (Sodium Hydroxide) NH4OH (Ammonium Hydroxide) Ca(OH)2 (Calcium Hydroxide) |
