Is NaCl acidic or basic?
Thus, salts consisting of these ions are neutral salts. For example: NaCl, KNO3, CaBr2, CsClO4 are neutral salts. When weak acids and bases react, the relative strength of the conjugated acid-base pair in the salt determines the pH of its solutions. The salt, or its solution, so formed can be acidic, neutral or basic.
Compare HCl, NaOH, and NaCl: HCl is a stronger acid than water. NaCl is a weaker base than NaOH. Strong acids react with strong bases to form weaker acids and bases. NH3 is a weak base, but its conjugate acid, NH4Cl, is a strong acid.
- NaOH, or sodium hydroxide, is a very strong base, like everyone else is saying. So if the NaOH were to neutralize with an acid like, say, hydrochloric acid (HCl), the resulting NaCl would be a salt. And since the reaction was between a strong acid and a strong base, the resulting salt is a neutral salt.
- Table salt, which is sodium chloride (NaCl), is not an acid or a base, but is a salt, as it is formed by the replacement of the H+ ion in Hydrochloric acid by sodium ion. But it will probably turn green as salts are usually neutral.
- The conjugate of a weak acid/base is not necessarily strong. For example, hydrochloric acid is strong, and upon dissociation chloride ions are formed. Chloride ions are a weak base, but the solution is not basic because the acidity of HCl is overwhelmingly stronger than basicity of Cl-.
Sodium chloride, which is obtained by neutralization of hydrochloric acid and sodium hydroxide, is a neutral salt. Neutralization of any strong acid with a strong base always gives a neutral salt. In general, however, salts may be acidic, basic or neutral. Let's investigate the pH of salts dissolved in water.
- The flame test is preformed by burning a metal salt using a flammable liquid. An alcohol is used to burn all of these salts, this one is sodium chloride (NaCl) which has a yellow flame.
- Question: Trimethylamine, (CH3)3N, is a weak base that ionizes in aqueous solution: (CH3)3N(aq) + H2O(l) (C A 0.120 M solution of (CH3)3N(aq) is 2.29% ionized at 25OC.
- For example, when ammonium chloride is dissolved in water, it gives an acidic solution because ammonium ion is a strong conjugate acid of the weak base ammonia, but chloride ion is a weak conjugate base of the strong acid hydrochloric acid.
Na and Cl can ionize, and produce Na+ and Cl- ions in water… which is the hallmark of salt behavior. But it is not an acid or a base. Some salts can be acidic or basic but NaCl is neither. In case of ph nacl has neutral ph due to neutralization of strong acid hcl and strong alkali naoh.
- There is a general rule in chemistry as to how salts affect solution pH. Sodium chloride is table salt and when it is added to water it breaks down into ions of sodium and chloride. Neither of them reacts to water so adding it to water will only change the volume, not the pH.
- The pH of seawater has remained steady for millions of years. Before the industrial era began, the average pH at the ocean surface was about 8.2 (slightly basic; 7.0 is neutral). Today it is about 8.1.
- Because all of the hydrogen chloride forms separate ions, hydrochloric acid is a strong acid. A weak acid does not form many ions in solution. Acetic acid (HC2H3O2) is the acid in vinegar.
