Is Ki an acid or base?
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. Therefore the solution will be basic, and KNO 2 is a basic salt.
Potassium bromide, a typical ionic salt, is fully dissociated and near pH 7 in aqueous solution. It serves as a source of bromide ions. This reaction is important for the manufacture of silver bromide for photographic film: KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)
- Potassium bromide (hydrobromic acid potassium salt) is a colorless crystalline substance, KBr. Potassium bromide is a typical ionic salt. In addition, it does not undergo hydrolysis as the salt has a strong base (potassium hydroxide) and strong acid (hydrobromic acid).
- Acid A substance which ionizes to form H+ (H+ is a product). Base A substance that accepts (reacts with) H+. Note that to obtain hydroxide ions (OH-) we start with an ionic compound that dissolves in water to form hydroxide ions, such as the alkali metal hydroxides, LiOH, NaOH, KOH, RbOH, etc.
- HCN, also known as hydrocyanic acid or prussic acid, is a weak acid. According to this source, the of HCN is 6.2 × 10 − 10 , which is really tiny. Memorize the short list of acids that are typically thought of as strong. This includes HCl, HBr, HI, HNO3, HClO3, HClO4, and H2SO4.
An aqueous solution of KC2H3O2 will be basic. The K+ is the cation of a strong base (KOH), thus it is a neutral ion and has no effect on the pH of the solution. The C2H3O2- is from a weak acid (HC2H3O2), thus it is a basic ion.
- Ammonium is formed by a weak base and is therefore a relatively stronger acid. Nitrate is formed from a strong acid and is therefore an extremely weak base. The overall compound is slightly acidic. The salt of a strong acid (HNO3) and a weak base (NH3) is acidic.
- It neither ionizes to form hydrogen ions, nor does it dissociates to give hydroxide ions. Therefore, it is neither an acid nor a base. In fact, CaCl2, or calcium chloride, is a salt.
