Chapter 1: Problem 59

The following data refer to the element phosphorus. Classify each as a physical or a chemical property. (a) It exists in several forms, for example, white, black, and red phosphorus. (b) It is a solid at \(25^{\circ} \mathrm{C}\) and \(1 \mathrm{~atm}\). (c) It is insoluble in water. (d) It burns in chlorine to form phosphorus trichloride.

Question: Classify the following properties of phosphorus as physical or chemical properties: (a) exists in several forms such as white, black, and red phosphorus, (b) solid at 25°C and 1 atm, (c) insoluble in water, and (d) burns in chlorine to form phosphorus trichloride. Answer: (a) Physical property, (b) Physical property, (c) Physical property, (d) Chemical property.

Step by step solution

01

Part (a) classification

We are given that it exists in several forms, such as white, black, and red phosphorus. Since these are different forms of phosphorus and do not represent a chemical change or reaction, this property is a physical property.
02

Part (b) classification

We are given that it is a solid at \(25^{\circ} \mathrm{C}\) and \(1 \mathrm{~atm}\). The state of matter (solid, liquid, or gas) at specific temperature and pressure is a physical property, as it does not involve any chemical change. Thus, this property is a physical property.
03

Part (c) classification

Phosphorus is stated to be insoluble in water. The solubility of a substance in a particular solvent is a physical property since it does not involve any chemical change when a substance dissolves in a solvent. Therefore, this property is a physical property.
04

Part (d) classification

It is given that phosphorus burns in chlorine to form phosphorus trichloride. This information describes a chemical reaction between phosphorus and chlorine, which leads to the formation of a new compound. Since this property involves a chemical change, it is a chemical property.

Potassium sulfate has a solubility of \(15 \mathrm{~g} / 100 \mathrm{~g}\) water at \(40^{\circ} \mathrm{C}\). A solution is prepared by adding \(39.0 \mathrm{~g}\) of potassium sulfate to \(225 \mathrm{~g}\) of water, carefully heating the solution, and cooling it to \(40^{\circ} \mathrm{C}\). A homogeneous solution is obtained. Is this solution saturated, unsaturated, or supersaturated? The beaker is shaken, and precipitation occurs. How many grams of potassium sulfate would you expect to crystallize out?
