WebWhile technically a weak acid, hydrofluoric acid is. Hydrocyanic acid is a colorless liquid whose vapor is lighter than air and dissipates rapidly. As per Bronsted-Lowry theory, HCN is an acid that donates one proton to a water molecule and forms a base (CN) known as the conjugate base of an acid(HCN). The chemical formula is shown below. WebWhichever is stronger would decide the properties and character of the salt. For example, NaOH + HCl = NaCl + H2O. Since both the acid and base are strong, the salt produced would be neutral. Strong base + strong acid = neutral salt. Strong base + weak acid = basic salt. Weak base + strong acid = acidic salt. Weak base + weak acid = neutral salt.
