Which ions are formed from the dissociation of the following compound?
A
Sr(OH)2 (s) → Sr2+ (aq) + 2 OH-
B
Sr(OH)2 (s) → Sr2+ (aq) + OH-
C
Sr(OH)2 (s) → 2 Sr+ (aq) + OH-
D
Sr(OH)2 (s) → 2 Sr+ (aq) + 2 OH-
Verified step by step guidance1
Identify the compound given: Sr(OH)2 is strontium hydroxide, a strong base that dissociates completely in water.
Understand the dissociation process: In aqueous solution, Sr(OH)2 dissociates into its constituent ions.
Determine the ions formed: Strontium hydroxide dissociates into one strontium ion (Sr2+) and two hydroxide ions (OH-).
Write the balanced dissociation equation: Sr(OH)2 (s) → Sr2+ (aq) + 2 OH- (aq).
Verify the charge balance: The total positive charge from Sr2+ is balanced by the total negative charge from two OH- ions, ensuring charge neutrality.
