Potassium hydroxide 0.1Н	10 ampoules	box

In agriculture, as a liquid fertilizer containing ammonium nitrogen 20.5%. From an economic point of view, this type of nitrogen fertilizers are the cheapest. The highest effect of the ammonia water is achieved by making the fall in the soil, because not washed away by precipitation, or preplant during the spring. Aqueous ammonia when applied to the soil can be used for all business culture. Nitrogen ammonia better retained soil than solid ammonium nitrogen fertilizers. Ammonia water - good fertilizer for potatoes, sugar beet, cereals and vegetable crops, perennial grasses. By increasing the yield of ammonia water is not inferior to solid ammonium nitrate fertilizers.

In animal husbandry - for ammoniation of forages.

In industry it is used in the manufacture of dyes, soda ash in the electric production of manganese ferroalloys, medical industry, household.

Available in two grades: A - for the industry, B - agriculture

Acids are substances that contain one or several hydrogen atoms, which, in chemical reaction, are likely to be substituted with metal atoms forming salts. Acids happen to be strong and weak, depending on dissociation. Typical properties of all acids are acid flavor and lacmus staining red. Acids have been known since ancient times. They are widely used in human everyday life.
