Definition: Having a high amount of substances that can neutralize acids, making a solution basic rather than acidic.

Example: The soil in this region is alkali, making it difficult for many plants to thrive.

Definition: This word describes a substance that has a pH level higher than 7, meaning it is not acidic. It often refers to solutions that can neutralize acids and may contain alkali metals.

Example: The alkaline solution was used to neutralize the acid.

Definition: Alkalinity is the measure of how much alkali is present in a substance, indicating its ability to neutralize acids. It describes the quality of being alkaline, which means having a pH level greater than 7.

Example: The alkalinity of the water was tested to ensure it was safe for aquatic life.

Definition: The process of changing a substance to make it more alkaline, which means it has a higher pH level and is less acidic.

Example: The alkalinization of the soil improved its fertility.

Definition: To change a substance so that it becomes more alkaline, which means it has a higher pH level and is less acidic.

Example: The chemist decided to alkalinize the solution to improve its effectiveness.

Definition: To make a substance more basic and less acidic.

Example: The scientist decided to alkalise the solution to improve its effectiveness.

Definition: To change into a substance that has a pH level greater than 7, making it less acidic.

Example: When the solution is heated, it will alkalize and become less acidic.

Definition: To change a substance so that it becomes less acidic and more alkaline, often by adding a base.

Example: The scientist decided to alkalize the solution to improve its effectiveness.

Example: Caffeine is a well-known alkaloid found in coffee and tea.

Definition: Relating to a group of natural compounds that often have strong effects on living organisms, commonly found in plants.

Example: The researchers studied the alkaloidal properties of the plant extracts.

Definition: A medical condition where the body's fluids have too much alkalinity, meaning they are less acidic than normal.

Example: The patient was diagnosed with alkalosis after the blood tests showed elevated pH levels.
