Which way of dissolving does NOT change the chemical identity of the solute?
disintegration
dissociation
ionization
dispersion
is it a?
if it disperses it just spreads out, does not change
thank you
No, it is not option A (disintegration). Disintegration refers to the process of breaking down into smaller pieces or fragments, but it does not involve a change in the chemical identity of the solute.
The correct answer is option D (dispersion). Dispersion refers to the process of spreading or dispersing the solute particles evenly throughout the solvent. It involves the physical separation of solute particles without any change in their chemical identity.
To determine which way of dissolving does NOT change the chemical identity of the solute, let's first understand each process:
1. Disintegration: This process involves the breaking up of solid particles into smaller pieces or fragments. However, the original chemical identity of the solute remains unchanged.
2. Dissociation: This process occurs when a compound breaks apart into its individual ions in a solvent. For example, when salt (NaCl) dissolves in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-).
3. Ionization: This process involves the formation of ions from molecules upon dissolving. It typically occurs with covalent compounds that undergo a chemical reaction with the solvent. One example is the ionization of water (H2O) into hydrogen ions (H+) and hydroxide ions (OH-) in an aqueous solution.
4. Dispersion: This process involves the distribution and dispersion of solute particles within a solvent without any significant chemical change. It commonly occurs with non-polar solutes, such as oil, which form droplets or micelles within a solvent.
Based on the explanations above, the correct answer is A) disintegration. Disintegration involves the physical breakdown of particles without any chemical changes, thus preserving the solute's original chemical identity.
