chemical principle

baking soda powder is actually sodium bicarbonate powder, the chemical formula is NaHCO?, Sodium is positively charged. If it is put into tap water, it will combine with the negatively charged chlorine in the water to form sodium chloride, which solves the problem of chlorine toxicity in tap water.

and hydrogen is positively charged. When it is added to water, it will combine with negatively charged water molecules and become weak alkaline water. Generally, most pesticides are acidic. Therefore, in addition to weak alkaline water and acidity, it can also accelerate the removal of pesticides attached to fruits and vegetables.

It can be used for apple, pear, kiwi, cucumber, carrot, wax gourd, pumpkin, zucchini, eggplant, radish, etc. During the treatment, it is necessary to prevent the vegetables, melons and fruits from being mixed and polluted again.

carbamate insecticides decompose faster with the increase of temperature. Therefore, for some vegetables and fruits which are difficult to be treated by other methods, some pesticides can be removed by heating. Commonly used in celery, spinach, cabbage, cabbage, green pepper, cauliflower, beans and so on.

wash the surface dirt with clean water, put it into boiling water for 2-5 minutes, and then rinse it with clean water for 1-2 times. According to the actual situation, the combination of the above methods will have a better effect.
