Verified step by step guidance1
Understand that potassium hydroxide is a compound made of potassium (K), oxygen (O), and hydrogen (H).
Recall that potassium (K) is an alkali metal that typically forms a +1 charge ion (K⁺).
Recognize that the hydroxide ion (OH⁻) is a polyatomic ion with a -1 charge.
Combine the potassium ion (K⁺) and hydroxide ion (OH⁻) in a 1:1 ratio to balance the charges, resulting in the formula \(KOH\).
Verify that the other options either have incorrect element symbols or incorrect ratios that do not represent potassium hydroxide.
