First, let's look at the list of ingredients: you need two things to make spout, either baking soda or cooking soda to neutralize the acidity. The main ingredient in baking soda is sodium bicarbonate, which is mild. Sodium bicarbonate and sodium carbonate are the main ingredients of cooking soda, which is more alkaline than baking soda. Therefore, when making Alkaline Water, if you are using baking soda, then the ingredients you need to prepare are baking soda and purified water; if you are using edible soda, then the ingredients you need to prepare are edible soda and purified water.
Then look at the production steps: according to a certain proportion of baking soda or edible alkali and pure water mixed together to complete the production of Alkaline water. The exact ratio depends on whether you are using baking soda or cooking soda: Alkaline = Baking Soda: Purified Water = 1:2; Alkaline = Cooking Soda: Purified Water = 1:4. So whether you are using baking soda or cooking soda, the ratio of mixing it with purified water is different, and will need to be determined based on the specific ingredients in the list of ingredients.
Overall, you can use either baking soda or cooking soda to make homemade spout, but it is important to note that the mixing ratios of the two with purified water are different, and also to determine the exact steps to make the spout based on the ingredients used.
