Sodium hydrogen carbonate (trivial name: sodium) has the empirical formula NaHCO3, is a sodium salt of carbonic acid and belongs to the hydrogen carbonates. The compound should not be confused with sodium carbonate (soda, molecular formula Na2CO3). Occasionally, the obsolete and chemically incorrect trivial names sodium bicarbonate and sodium bicarbonate are also used for sodium hydrogen carbonate. The compound is also offered on the market under the names soda-ash, baking soda, soda-ash and brand names.
Sodium hydrogen carbonate can be used in many ways.
As a remedy for heartburn. For bathing, to deacidify the body, to brush the teeth.
Excess acid in food is neutralized or weakened by sodium bicarbonate. This is important, for example, in the preparation of jams from sour fruits such as sea buckthorn or rhubarb, as this gives them a milder taste and reduces the need for sugar. Even vinegar or lemon juice excessively added to a dish can be neutralised by sodium bicarbonate. A pinch of baking soda in the cooking water softens peas, lentils and beans more quickly and reduces the bloating effect of various cabbage varieties.
In the household:
For softening water, for example to make tea or coffee. As an addition to laundry.
As a cleaning agent for removing crusted food residues: powder the bottom of the pot with baking soda, leave to stand and boil with water. Suitable for stainless steel and enamel pots, thermos flasks, teapots, flower vases.
It neutralizes odors:
bad breath, drainage pipes, musty shoes, refrigerator, cat toilet, small animal cages.
Sodium hydrogen carbonate is a plant strengthening agent. When dissolved in water, it strengthens the resistance of plants to powdery mildew, downy mildew and grey rot. Plant strengthening agents strengthen the resistance of plants to pests and diseases. For humans, their pets and the surrounding environment, these substances are harmless and are degraded without leaving residues within a short period of time.
Approved as a basic substance (EU Plant Protection Products Ordinance 1107/2009) and may now officially be used as follows:
Sodium hydrogen carbonate is approved as a fungicide for combating mildew in various horticultural crops, for combating apple scab, for post-harvest treatment of fruit and vegetables against storage diseases.
Sodium hydrogen carbonate is a special sodium salt of carbonic acid, which can be used completely safely and without side effects for humans and the environment.
In the last 15 years it has also been used under the name "Steinhauer´s Mehltauschreck" as a plant strengthening agent in agriculture to combat powdery mildew and downy mildew. This effect was discovered before approximately 100 years by a German pharmacist, who protected already at that time its rose bushes and fruit trees against the dreaded mushroom diseases pollution-free and without side effects. Flour de-icing salt is dissolved in water and sprayed dripping wet onto the plants. This increases the pH value on the leaf surface and makes it more difficult for powdery mildew fungi to adhere to the plants.
Mildew fungi are among the best-known and most widespread plant diseases. Mildew infestation is usually visible on the upper side of the leaves due to a powdery, whitish coating. A small initial infestation can spread extensively within a few days. Powdery mildew severely damages plants. In the case of useful plants, the yield is reduced and in many cases the harvest is completely destroyed. In ornamental plants such as roses, the damage is shown by pale flowers and wilted leaves.
Application and dosage:
For better adhesion the sodium hydrogen carbonate should be used together with a vegetable oil - e.g. neem oil - and an emulsifier - e.g. the neem oil emulsifier "Rimulgan". This combination forms a wafer-thin coating on the leaves and thus ensures even distribution and good adhesion of the sodium hydrogen carbonate. All these substances are non-toxic for humans and their pets and their use is beneficial to the animals.
1. mix vegetable oil and emulsifier into formulated oil.
2. prepare the spray liquid: dissolve sodium hydrogen carbonate in water, then stir in the formulated oil.
3. apply dripping wet with a sprayer.
Repeat the treatment every 7 - 14 days.
Dosage per litre of spray liquid:
Roses, fruit trees, shrubs 5 - 10 g flour de-icing salt + 5 - 10 ml formulated oil
Vegetables, salad 2.5 - 5 g flour de-icing salt + 5 ml formulated oil
viticulture 5 - 10 g flour de-icing salt + 5 ml formulated oil
