- Q: Who can tell me what is plant alkalinity?
- A basic nitrogen - containing organic compound in a living organism. Most of them exist in plants and are present in animals. With a ring structure, insoluble in water, and acid can form a salt, a certain optical and absorption spectrum, most of the bitter taste, was colorless crystal, a small number of liquid.
- Q: I have been very confused, baking soda and edible alkali surface is the same thing? Tea in the consumption of baking soda is not become alkaline? Can drink? How to quickly become alkaline? In addition to more melon Fruit and vegetables outside
- Baking soda is not edible.
- Q: What is alkali sand
- Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.
- Q: How does the edible base use?
- Avoid the food on the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated several times the raw material can be;
- Q: Alkaline pool can breed what
- In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.
- Q: Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?
- What to eat is more harmful. So you can add the same time while paying attention to the diversity of the diet.
- Q: A bit tall please help me one!
- As a result of the community on the misuse of waste batteries, such as: a button battery can pollute 600,000 cubic meters of water, a 5-cell can make a square meter of land is not grass, resulting in some public opinion bias, so that our waste disposable battery recycling And chaos dealing with the work, resulting in some unnecessary waste and mistakes.
- Q: What is the use of alkali?
- From acid and alkali combined effect
- Q: What is the harm to the human body?
- Almost no harm, accidentally get the body, with water; with a small amount of dilute sulfuric acid wash on the line, do not worry to the hospital point of medicine, half of nothing
- Q: What is the alkaline powder? Baking soda? Sodium carbonate or something else?
- Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be
