Bases are bitter in taste, slippery in touch and turns red litmus paper to blue. They contains hydroxide ion OH- and when they are dissolved in water, bases produces this ion. The production of hydroxide ion determines that a solution is basic in nature. When base is reacted with acid, in most of the case the resultant product is water as the H+ ion from acid combines to OH- ion of base to form .
<em>Bases are those substances that have </em><u><em>hydroxyl ions</em></u><em> present in it.</em>
Explanation:
When these bases dissolve in water then they tend to separate from the base and yield hydroxide ions.
For instance, sodium hydroxide- There are certain bases that do not have hydroxide ion present in it but still acts as a base because they tend to remove hydrogen ions from the water molecule when dissolved in water.
For instance, Ammonia - it does not have hydroxide ion but still acts as a base.
<em><u>There are two important types of genetic mechanisms that can give rise to antibiotic resistance: mutation and acquisition of new genetic material. In the case of mutation, the rate at which resistance develops can be attributed to the rate at which bacteria mutate.</u></em>
Neap tides are when the tidal movement is affected in the least magnitude by the moon.. This happens just after the moon is in its first and third quarter. So roughly every fornight
