base

Potassium cyanide (KCN) is a salt formed by the reaction of a strong base, potassium hydroxide (KOH), with a weak acid, hydrocyanic acid (HCN). As a result, KCN is considered a weak base. In aqueous solutions, KCN dissociates into potassium ions (K+) and cyanide ions (CN-). The cyanide ion is a weak base and can accept protons (H+) from water to form hydroxide ions (OH-). This increases the pH of the solution, making it slightly alkaline....
