Potato is a nutritious food, which is rich in starch, vitamin C, protein and polysaccharide. Walnut is a typical alkaline food, which can help the human body to supplement some necessary trace elements. Mushroom is one of the staple foods of one of the top ten alkaline foods. Mushrooms are rich in inorganic substances, vitamins, protein and other rich nutrients. They are low in calories and will not gain weight if eaten frequently.
Bread is a healthy alkaline staple food, and the carbohydrate content of flour is high. Soybean milk is a traditional drink made of soybean and water by grinding and boiling. Tofu is a kind of food made of soybean and water as the main ingredients and condensed with gypsum or brine.
Soybean is a kind of leguminous food originated in China, with a cultivation history of more than 5,000 years. Almond is a kind of nut variety rich in oil, although it is not suitable to eat more, but a small amount of it contains a variety of mineral elements and vitamins; Coriander is a kind of nutritious food, and its unique flavor and taste are also deeply loved by people. Pumpkin seed is one kind of pumpkin pulp, which is rich in fatty oil and presents a yellow-white oval shape after drying.
Basic introduction of alkalinity
For a substance, whether it is alkaline depends on the ability of unpaired electrons to accept protons. For example, in aqueous solution, OH- ions can accept H+ and NH4+ plasma, thus showing alkalinity. Accordingly, in non-aqueous systems, such as in liquid ammonia solvent, NH2- ions can accept NH4+ plasma and also show alkalinity.
Generally speaking, the alkalinity of a substance depends on its proton-accepting ability and the stability of the formed atomic groups. For example, NH3 can accept BF3 to form BF3+NH3-, but the stability of this ion is poor, so NH3 is weakly alkaline. When NH2- accepts H+, it forms stable NH3, so NH2- is strongly alkaline. In aqueous solution, NaOH is as alkaline as KOH, so it is called leveling solvent, but in some solvents, it can show different alkaline differences, so it is called distinguishing solvent.
The stronger the metallicity of an element, the stronger the alkalinity of the hydrate of its highest valence oxide; The stronger the nonmetallic nature of the element, the stronger the acidity of the hydrate of the highest valence oxide.
