Abstract: Mineral salts containing potassium are all potassium salts. Common ones include potassium rock, potashite, carnallite, magnesium sulfate and potassium chloride. Compared with sodium salt, the main differences between potassium salt and sodium salt are solubility, hygroscopicity and crystal water. As a mineral salt, the vast majority (95%) of potassium salt products are used as fertilizers, but there are also a small amount of potassium salts that are not potash fertilizers but are industrial products. Let’s learn about the difference between potassium salt and sodium salt and the difference between potassium salt and potassium fertilizer. 1. What is potassium salt

Potassium salt is a mineral salt, which refers to natural potassium-containing minerals. It is divided into soluble potassium salt minerals and insoluble potassium-containing aluminum silicate minerals, including potassium stone. Rock, magnesium alkali, carnallite, magnesium sulfate and potassium chloride are all potassium salts.

2. What are the differences between potassium salt and sodium salt?

Both potassium salt and sodium salt are mineral salts, but there are big differences between them, which are mainly reflected in the following Several aspects:

1. Different solubility

The solubility of sodium salt is greater than that of potassium salt, but the solubility of sodium bicarbonate in sodium salt is relatively small, while the solubility of chlorine salt is relatively small. The solubility of sodium chloride does not change with temperature.

2. Different hygroscopicity

Sodium salt is more hygroscopic than potassium salt, so potassium salt is easier to store. If sodium salt is not stored properly, it will easily become damp and deteriorate. .

3. Crystal water is different

The sodium salt containing crystal water will be more than the potassium salt. For example, anhydrous sodium sulfate can easily absorb water and form compounds, usually about 3/4 The sodium salt contains crystal water, and only 1/4 of the potassium salt contains crystal water.

3. What is the difference between potassium salt and potassium fertilizer

1. Potassium salt

Potassium salt is a chemical substance that contains Potassium salts, all mineral salts containing potassium can be called potash salts, 95% of the world's potassium salt products are used as fertilizers, and 5% are used in industry.

2. Potassium fertilizer

Potassium fertilizer is one of the three major agricultural fertilizers. It refers to chemical fertilizers containing potassium and has a significant yield-increasing effect on most crops. Potassium fertilizer is mainly potassium chloride. and potassium sulfate, which are acidic fertilizers.

To sum up, potash fertilizer belongs to the category of potassium salts. Most potassium salt products are potash fertilizers, but not all potassium salts can be used as potassium fertilizers.
