What is an antifreeze?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Antifreeze**: An antifreeze is a substance that is added to water to lower its freezing point. 2. **Function of Antifreeze**: The primary function of antifreeze is to delay the freezing of water. This is particularly important in various applications, such as in vehicles, to prevent the engine coolant from freezing in cold temperatures. 3. **Examples of Antifreeze**: Common examples of antifreeze include: - **Sodium Chloride (NaCl)**: Commonly known as table salt, it is often used in winter to melt ice on roads. ...

    The boiling point elevation and freezing point depression of solutions have a number of partical applications. Ethylene glycol (CH_(2)OH-CH_(2)OH) is used in automobile radiatiors as an antifreeze because it lowers the freezing point of the coolant. The same substance also helps to prevent the radiator coolant from boiling away by elevating the boiling point. Ethylene glycol has low vapour pressure. We can also use glycerol as an antifreeze. In order for the boiling point elevation to occur, the solute must be non-volatile, but no such restriction applies to freezing point depression. For example, methanol (CH_(3)OH) , a fairly volatile liquid that boils only at 65^(@)C , is sometimes used as an antifreeze in automobile radiators. If the cost of glycerol, glycol, and methanol is same, then the sequence of economy to use these compounds as antifreeze will be
