What substance completely dissociates into ions 1) barium chloride 2) carbon disulfide 3) carbonic acid 4) sucrose
| April 8, 2021 | education
Dissociation is the breakdown of electrolytes into ions when dissolved in water or melted. The electrolytes are WATER-SOLUBLE SALTS, ACIDS, BASES. All other substances cannot dissociate into ions.
1) Ba (OH) 2 = Ba (+2) + 2 OH (-), since barium hydroxide is a soluble base.
2) Carbon disulfide CS2 is not an electrolyte.
3) Н2СО3 = 2Н (+) + СО3 (-2), since carbonic acid is soluble.
4) Sucrose is a carbohydrate with a molecular crystal lattice that dissolves in water, but does not dissociate.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
