An alkali is a substance that produces hydroxide ions (OH-) in solution, while alkaline refers to a substance that has a pH greater than 7. Therefore, alkalis are a type of alkaline compound due to their ability to increase the pH of a solution.
Sharpness is a sensory perception related to taste and has nothing to do with being an acid or alkaline substance. pH is used to determine if a substance is acidic (pH below 7), neutral (pH of 7), or alkaline (pH above 7).
Alkaline substances have a high pH, typically above 7 on the pH scale. A pH value greater than 7 indicates that a substance is basic or alkaline.
A pH range of 7.01 to 14 indicates that a solution is alkaline. Solutions with a pH above 7 are considered alkaline.
One way to tell if something is alkaline is by using pH test strips or a pH meter to measure the pH level of the substance. If the pH is above 7, it indicates alkalinity. Another method is to observe if the substance feels slippery, which is a common characteristic of alkaline solutions.

the higher the pH, the more alkaline the substance is. :)

If a substance has a pH of 5, it is said to be weakly acidic.
A substance with a pH of 13.0 is considered highly basic. This pH level indicates that the substance is strongly alkaline.
Water is considered neutral, with a pH of 7. It is neither acidic nor alkaline.
No, they are not the same. "Basic" refers to a substance with a pH greater than 7, while "alkaline" specifically refers to a substance that is a base or has a pH higher than 7. All alkaline substances are basic, but not all basic substances are alkaline.
No, a substance cannot be both acidic and alkaline at the same time. Acidity and alkalinity are opposite characteristics on the pH scale, ranging from 0 to 14. A substance that is acidic will have a pH below 7, while a substance that is alkaline will have a pH above 7.
No. A higher pH simply means a substance is more alkaline and less acidic.
