Chapter 22, Problem 76
Complete the exercises below. a. Determine the number of sodium ions in the chemical formula of albite, NaₓAlSi₃O₈ b. Determine the number of hydroxide ions in the chemical formula of tremolite, Ca₂Mg₅(Si₄O₁₁)₂(OH)ₓ.
Verified step by step guidance1
Step 1: Identify the chemical formula of albite, which is NaAlSi₃O₈. Notice that the subscript for sodium (Na) is 1, indicating there is one sodium ion per formula unit of albite.
Step 2: For tremolite, examine the chemical formula given: Ca₂Mg₅(Si₄O₁₁)₂(OH)ₓ. The subscript 'x' next to the hydroxide ion (OH) indicates the number of hydroxide ions present.
Step 3: Recognize that the chemical formula of tremolite is typically written as Ca₂Mg₅(Si₄O₁₁)₂(OH)₂, meaning there are 2 hydroxide ions per formula unit.
Step 4: Understand that the subscript 'x' in the problem is a placeholder for the actual number of hydroxide ions, which is 2 in the case of tremolite.
Step 5: Conclude that the number of sodium ions in albite is 1, and the number of hydroxide ions in tremolite is 2.
