The traditional scooping water is plant ash lixivium, but now scooping water is a compound alkaline solution with potassium carbonate and sodium carbonate as the main components, which can also be replaced by soda water in household use. Edible soda ash and clean water are mixed in the ratio of1:3 ~ 4 to prepare an aqueous solution with a pH of about 12.6, and the effect of replacing scooping water with this aqueous solution is also very good.

Substitute for scooping water-edible alkali solution;

Edible alkaline flour is NA2CO3, also known as soda and soda ash, and its scientific name is sodium carbonate, which is used to neutralize excess acidity when using traditional flour fat to make flour. After checking all kinds of data, it is found that the ph value of saturated sodium carbonate solution is about 12 at room temperature, while the solubility of sodium carbonate at 30℃ in summer is 39.7g/ 100g of water, and the approximate ratio is about 1:3. Then the edible alkali 1:3 is dissolved in water and filtered. For example, 2 grams of water is mixed with 0.5 grams of soda ash powder and 1.5 grams of water. If there is a large amount, 250g of edible alkali block can be added with 500ml of boiling water and stirred until it is completely dissolved and has a medium concentration. After being adjusted, it can be stored in glass bottles. (Because too much crystals will precipitate automatically, it won't cause too high concentration, and it will automatically saturate.)

Substitute for scooping water-baking soda solution;

Baking soda is sodium bicarbonate, also known as acid sodium carbonate, which is an acid salt with the chemical formula of NaHCO3. It can usually be used to make bread and soda. At room temperature, the ph value of saturated sodium bicarbonate solution is about 10, so it feels that edible alkali solution is more suitable. Melt with 1/2 tsp baking soda and 1 tsp water, and then take the clear liquid.
