A general term for basic substances that dissolve in water, such as sodium hydroxide, potassium hydroxide, and slaked lime, which neutralize acids and result in salt formation.
Refers to a specific group of soft, silvery-white metallic elements, including lithium, sodium, and potassium, characterized by their lightness and their vigorous reaction with water, producing strong alkaline hydroxides.
The property of substances that can change red litmus paper to blue, indicating their ability to neutralize acids, contrasting with acidic properties.
Foods that are high in alkaline minerals such as sodium, potassium, and calcium, including various vegetables, fruits, and dairy products, promoting an alkaline environment in the body.
A type of hot spring that contains alkali, known for its therapeutic benefits particularly for conditions affecting the digestive system and women's health.
A characteristic of substances that can neutralize acids, often resulting in a chemical reaction that forms salts, and is indicated by a change in color of pH indicators such as turning red litmus paper blue.
The quality of being basic, where the presence of alkaline substances causes an increase in pH levels in solution, setting it apart from acidic properties.
Referring to various compounds, especially those containing specific metals like sodium and potassium, which react vigorously with water to produce strong bases.
A term associated with certain foods that, when metabolized, contribute to an alkaline environment in the body, often including items such as fruits, vegetables, and dairy products.
Example:
小学校のときから、酸性・アルカリ性という性質をリトマス紙で調べたりしてきていますね。
A group of six metallic elements in the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium—that are characterized by their lightness, softness, and distinct silvery-white appearance.
Elements that readily react with water to produce strong alkaline hydroxides, while also exhibiting a notable tendency to lose an electron and form positive ions.
Metals that belong to Group 1 of the periodic table, known for their high reactivity and ability to change the color of litmus paper from red to blue, indicating their basic properties.
Soft, lightweight metals that are found in nature primarily in their ionic form and are essential in various chemical reactions, particularly due to their strong basic characteristics when dissolved in water.
Elements with a unique flame test coloration that serves as a distinguishing feature, indicating their presence in various chemical compounds and reactions.
