which bronsted lowry acid has the strongest conguate acid?
acetate ion
flouride ion
cyanide ion
nitrate ion
not flouride that's for sure
To determine which Bronsted-Lowry acid has the strongest conjugate acid, we need to compare the stability of their conjugate acids. The stronger the acid, the weaker its conjugate base (conjugate acid being the species formed when an acid donates a proton).
To assess the stability of conjugate acids, we can consider the electronegativity and the size of the conjugate base.
Acetate ion (CH3COO-) - The conjugate acid is acetic acid (CH3COOH). The stability of acetate ion increases by resonance due to the presence of the electron-donating methyl group. The conjugate acid, acetic acid, is a weak acid.
Fluoride ion (F-) - The conjugate acid is hydrofluoric acid (HF). Fluoride ion is a weak base due to its small size and high electronegativity. Therefore, its conjugate acid, hydrofluoric acid, is a weak acid.
Cyanide ion (CN-) - The conjugate acid is hydrogen cyanide (HCN). Cyanide ion is a strong base due to its negative charge and availability of an electron pair. Therefore, its conjugate acid, hydrogen cyanide, is a weak acid.
Nitrate ion (NO3-) - The conjugate acid is nitric acid (HNO3). Nitrate ion is a weak base due to its resonance structure and negative charge being spread over multiple atoms. Therefore, its conjugate acid, nitric acid, is a strong acid.
Based on this analysis, the nitrate ion (NO3-) has the strongest conjugate acid among the given options.
