Chapter 22, Problem 75
Complete the exercises below. b. Determine the number of hydroxide ions in the chemical formula of the mineral pyrophyllite, Al₂(Si₂O₅)₂(OH)ₓ.
Verified step by step guidance1
Identify the chemical formula of pyrophyllite: Al₂(Si₂O₅)₂(OH)ₓ.
Recognize that the subscript 'x' in (OH)ₓ represents the number of hydroxide ions in the formula.
Understand that the chemical formula provides the ratio of atoms in the compound, and the subscript 'x' indicates how many hydroxide ions are present.
To determine the value of 'x', you may need additional information such as the charge balance or empirical data about the mineral.
If no additional information is provided, the problem may be asking for a theoretical understanding of how to interpret the formula, focusing on the role of 'x' in representing the number of hydroxide ions.
