What is the formula of chemical solubility in grade three?

Potassium sodium ammonium salt dissolves in water quickly, and barium, silver, lead and calcium are precipitated by sulfuric acid. Chlorine salt is insoluble in silver chloride, and nitrate solution is transparent. Alkaline solution of lithium, potassium, sodium, barium and ammonia, the molecular formula is not mentioned.

Equation 2:

Potassium, sodium, ammonium salts and nitrates; Removing silver and mercury by chloride; Removing barium and lead with sulfate; Carbonic acid, phosphate, only soluble in potassium, sodium and ammonium.

Formula 3:

Potassium, sodium, ammonium and nitrate are all soluble, but chloride does not dissolve silver and mercury; Sulfate does not dissolve barium and lead, and carbon phosphate is mostly insoluble. Most acids are soluble in alkali, but only potassium, sodium, ammonium and barium are soluble.

Equation 4:

Potassium, sodium and nitric acid are soluble, while potassium, sodium and nitrate are all soluble in water. Except silver (mercuric chloride), hydrochloric acid is soluble except silver chloride and mercurous chloride.

Explanation:

1 and potassium, sodium and ammonium salts are all soluble in water.

2. Only barium sulfate and lead sulfate are insoluble in sulfate (slightly soluble calcium sulfate and silver sulfate will also precipitate).

3. Nitrates are all soluble in water.

4. Besides potassium ions, sodium ions, ammonium ions, lithium ions and barium ions, alkaline substances are also soluble.

5. The salt not involved in the formula is insoluble in water.
