In general, liquid and liquid are miscible with each other, and water is often regarded as a solute in the presence of water, and more is regarded as a solute in the absence of water, so water and alcohol are often miscible with water as a solute.

Sucrose is an organic substance that is much more soluble in water than salt (a simple ionic compound) and like alcohol, it is also an organic substance that can be miscible with water in any proportion (most of the time, with a few exceptions).

The solute is alcohol and the solution is wine.

Sucrose has a high solubility.

Alcohol Medical alcohol.

Sucrose sucrose grams.

Grams of sodium chloride.

When two liquids dissolve each other, the one with the largest amount is usually called the solvent and the one with the small amount is called the solute. However, when liquids and water dissolve into each other, it is common to think of water as a solvent, regardless of its content.

A homogeneous and stable mixture formed by the dispersion of one or more substances into another substance is called a solution. Various solutions such as hydrochloric acid, dilute sulfuric acid, ammonia, etc., are often used in industrial and agricultural production and laboratories. In medical treatment, many drugs are often used as solutions, such as normal saline, glucose injection, eye drops, etc.

Wine, vinegar, sugar water, salt water, etc. used in family life. We divide the solution into solute and solvent parts. In solution, the substance that can dissolve other substances is called solvent, and the substance that is dissolved is called solute.

Solvents are generally liquids. Water dissolves many substances and is the most commonly used solvent. A solution that uses water as a solvent is called an aqueous solution.

Gasoline, alcohol, benzene, acetone, etc. can also be used as solvents. For example, gasoline dissolves grease and fat, alcohol dissolves iodine, chloroform (chloroform) dissolves plexiglass, etc. This type of solution prepared with a non-aqueous solvent is called a non-aqueous solution.

The solute can be solid, liquid or gaseous. When solids and gases are dissolved in liquids, solids and gases are solutes and liquids are solvents. When two liquids dissolve each other, the one with the largest amount is usually called the solvent and the one with the small amount is called the solute.

However, when liquids and water dissolve into each other, it is common to think of water as a solvent, regardless of its content.

At room temperature, at 10 o'clock, the solubility of table salt is 35 grams, and the solubility of table salt at room temperature is 36 grams. Solubility of sucrose: 179g at 0, room temperature; 487g at 100 hours.

Alcohol and water are solvents, no matter how much alcohol or water.

For the first time, the speed of light 3x10 to the power of 5 kms per second multiplied by the 7th power = x10 to the 15th power m = 12 square kilometers.

Question 2: Use 12 to the power of KMx500 years = 14 km to the power of 14 km. Look

1) (2) Exploit one light year in (1) = so.

1..There must be: potassium carbonate, definitely not:

Calcium carbonate, copper sulfate, magnesium chloride, possibly: sodium nitrate 2There must be:

Sodium carbonate, barium nitrate, certainly not: copper sulfate, possibly: potassium chloride 3

Ken or Hui must have: sodium carbonate, potassium chloride, certainly not: copper sulfate, barium sulfate, calcium chloride, there may be:

Sodium nitrate.
