What is ammonium bicarbonate and how to choose ammonium bicarbonate? Is it acidic or alkaline?

Ammonium bicarbonate is a white compound, which is generally used as nitrogen fertilizer in rural areas.

This paper explains what ammonium bicarbonate is, how to choose ammonium bicarbonate and whether ammonium bicarbonate is acidic or alkaline for your reference.

1. What is ammonium bicarbonate?

Ammonium bicarbonate is a white compound, which belongs to carbonate. It is a granular, flaky or columnar crystal, non-toxic, with ammonia smell, soluble in water and insoluble in ethanol.

The aqueous solution is alkaline, weak in alkalinity and easy to absorb moisture and agglomerate.

Ammonium bicarbonate can be used as nitrogen fertilizer, analytical reagent, aerator, food expansion agent, raw material of foaming powder juice, medical reagent, and used in plastic and rubber industry, ceramics, chrome tanning and synthetic catalyst.

2. Is ammonium bicarbonate acidic or alkaline?

Ammonium bicarbonate is a weak acid and weak base salt, which is close to neutrality, but its solution is alkaline after hydrolysis.

When the temperature reaches above 36℃, ammonium bicarbonate will be decomposed into carbon dioxide, ammonia and water, and when the temperature reaches 60℃, ammonium bicarbonate will be completely decomposed.

Advantages and disadvantages of ammonium bicarbonate fertilizer

1. Advantages of ammonium bicarbonate ammonium bicarbonate is quick-acting, cheap and does not harden the soil. It can be directly absorbed by crops and can take effect on the same day. It is one of the quick-acting fertilizers.

When ammonium bicarbonate is applied to soil, it can quickly kill or drive away pests and poison harmful bacteria.

2. Disadvantages of ammonium bicarbonate: the nitrogen content of ammonium bicarbonate is low, only 65,438+07%, the fertilizer efficiency time is short, and it is volatile and easy to lose in soil.

In addition, ammonium bicarbonate is unstable, and it is easy to absorb moisture in the air during storage, which leads to the phenomenon of ammonium bicarbonate caking.

4. How to choose ammonium bicarbonate fertilizer for agricultural use can generally make a preliminary identification of its authenticity and quality through four steps: seeing, smelling, distinguishing and dissolving.

1 Look

Ammonium bicarbonate generally has two colors: agricultural ammonium bicarbonate obtained by absorbing carbon dioxide from ammonia water is translucent crystal, while granular ammonium bicarbonate produced by adding auxiliary materials is opaque white particles.

Step 2 smell

Ammonium bicarbonate has a strong pungent ammonia smell, but the ammonia smell of granular ammonium bicarbonate produced by adding auxiliary materials is much smaller, and the more auxiliary materials are added, the less obvious the ammonia smell is.

squeeze

Ammonium bicarbonate fertilizer feels like sand when pinched by hand, but the granular ammonium bicarbonate produced by adding auxiliary materials feels hard when pinched by hand and is not easy to crush.

Step 4 dissolve

Ammonium bicarbonate is easily soluble in water, but the granular ammonium bicarbonate produced by adding auxiliary materials dissolves slowly.
