Identify the chemical formula for each compound: KOCH₃ and CH₃OH.
Determine the nature of KOCH₃: Potassium methoxide (KOCH₃) is a salt formed from potassium (K⁺) and methoxide (CH₃O⁻). Methoxide is a strong base because it is the conjugate base of methanol (CH₃OH), which is a weak acid.
Classify KOCH₃: Since methoxide is a strong base, KOCH₃ is classified as a strong base.
Determine the nature of CH₃OH: Methanol (CH₃OH) is an alcohol, not an acid. It does not dissociate in water to produce H⁺ ions, so it is not classified as an acid or base in the traditional sense.
Classify CH₃OH: Methanol is not an oxyacid; it is a neutral compound and does not fit the classification of strong or weak acid/base.
